Top 10 Mistakes When Migrating From Oracle to PostgreSQL

PGConf US and Austin PUG organized a PGConf Mini last night. It was three presentations over the evening. We had good attendance and excellent community participation. The highlight of the evening was PGConf US Co-Chair Jim Molgendski's presentation, "Top 10 Mistakes When Migrating from Oracle to PostgreSQL".

We tried something new this time around. We utilized Twitter's Periscope capability to live stream his presentation. It wasn't perfect but it was our first time and we are looking forward to utilizing the platform more in the future.

Click here to watch "To Mistakes When Migrating From Oracle to PostgreSQL", and then submit a presentation to one of our upcoming conferences:

People, Postgres, Data


People, Postgres, Data is not just an advocacy term. It is the mission of PostgresConf.Org. It is our rule of thumb, our mantra, and our purpose. When we determine which presentations to approve, which workshops to support, which individuals to receive scholarships, which events to organize, and any task big or small, it must follow: People, Postgres, Data. It is our belief that this mantra allows us to maintain our growth and continue to advocate for the Postgres community and ecosystem in a positive and productive way.

When you attend PostgresConf the first thing you will notice is the diversity of the supported ecosystem; whether you want to discuss the finer points of contribution with the major PostgreSQL.Org sponsors such as 2ndQuadrant or EnterpriseDB, or you want to embrace the Postgres ecosystem with the Greenplum Summit or TimeScaleDB.

The following is a small sampling of content that will be presented April 16 - 20 at the Westin Jersey City Newport:

Community member profile: Darren Armani & Vertex Enterprise 






Why did you attend PgConf US?

Our company is exploring the use of PostgreSQL as an additional DBMS choice to support Vertex Enterprise, our tax technology platform. Attending the conference offered me an opportunity to immerse myself into a variety of topics around PostgreSQL, as well as the chance to interact with other users to tap into their experiences.


Tell us a little bit about your project or how you use PostgreSQL:


Vertex Enterprise is a global tax management end-to-end solution that integrates all tax processes with Enterprise Resource Planning (ERP) and business intelligence (BI) systems on a single platform using a tax performance engine.   The solution is a blend of technologies that surround a Java based processing and calculation engine. This includes rich UI's, import, export, business intelligence / reporting, and big data integration. The foundation of our database leverages a multi-dimensional database structure, as well as other structures whose design varies based upon the needs of a particular function so that we can optimize performance. (ie. import/export/reporting).

The official brochure provides a high level overview of the capabilities and interfaces that our DBMS must support.  


Why did you chose PostgreSQL for your project?


PostgreSQL checks many of the boxes that we are looking for in our consideration of an additional DBMS option.


Some of these include:


* Performance
* Lower cost
* Multi-tenancy support 
* Suitable for deployment on premise, in a hosted environment, and in the cloud
* Industry acceptance
* Ease of administration on locally administered instances
* Features characteristic of an enterprise strength database (auditing, partitioning, replication, procedural language support)


This was your first PGConf US, was it a last minute decision? Do you think it was worth it? If so, why?


The conference was on our radar since the beginning of the year, and it exceeded expectations. Listening to and interacting with actual contributors to the product is not something you have the opportunity to do at many conferences. The sessions covered a variety of topics around PostgreSQL that were of interest (performance, tuning, feature discussion, lessons learned, cloud deployment options, optimization, etc).


Would you attend PgConf US again?


Yes, definitely. 


Are you interested in contributing to the community and if so, in what fashion?


My "day job" keeps me pretty busy, but as far as sharing our experience with PostgreSQL, I am willing to contribute in that way :) .

Great content

Extension Highlight

We wanted to highlight some of the fantastic work that is being done by the ecosystem with Postgres Extensions. Although the base of Postgres is the amazing and extensible PostgreSQL, a lot of users don’t realize that Postgres has the feature they are looking for, if only they were to look to the ecosystem.

Notable Extensions:

  • pgaudit : The goal of pgAudit is to provide PostgreSQL users with the capability to produce audit logs often required to comply with government, financial, or ISO certifications.

  • pg_credereum : pg_credereum is a PostgreSQL extension that provides a cryptographically verifiable audit capability for a PostgreSQL database, bringing some properties of blockchain to relational DBMS.

  • H3-pg : PostgreSQL bindings for H3, a hierarchical hexagonal geospatial indexing system.

Postgres can do what?

There are a ton of Postgres compatible features out there. Some of them are overlooked core features and some of them require installing a different version of Postgres. Here are a few examples:

 

  • TimescaleDB: Time series data management with Postgres

  • YugabyteDB: Globally Distributed database with PostgreSQL compatibility

  • Postgres-XL: Horizontally partitioned PostgreSQL

  • Agensgraph: Graph capabilities with Postgres

  • PG-Strom: GPU accelerated extension for Postgres 

 

Upcoming Education and Networking opportunities:

Rescheduled: PGConf US Local: Seattle and PGConf US Local: Austin

Community,


The Chairs of PGConf US have rescheduled the Seattle and Austin Local events. After much deliberation we believe moving the events to a weekday format later in the year will offer a better opportunity for those who wish to attend.

New dates:
  • Seattle: November 13th and 14th, 2017
  • Austin: December 4th and 5th, 2017
The CFP for Seattle is closed but Austin is still open!

An act of kindness for the PostgreSQL community

Since at least 2021 there has been a disagreement between Postgres related non-profit organizations. On one side are two affiliate non-profits for Postgresql.org; on the other is a relatively unknown non-profit out of Spain. Lines have been drawn, feet have dug in, and a lot of unproductive discourse has occurred. This has culminated in legal action, bad blood, and some poor decisions. 

As one of the Founders of United States PostgreSQL, a former Director of Software in the Public Interest (one of the NPOs behind Postgresql.org), a former committer (web), former major contributor, President of the oldest PostgreSQL company still independent in North America, and the Founder of Postgres Conference (in the U.S.), I thought I would offer a knowledgeable perspective. 


I have had long discussions with one of the primary people within the Fundacion PostgreSQL  (Alvaro) and his heart is in the best interest of the community, even if Postgresql.org, PGEU and PGCAC do not agree. You can see this demonstrated within Fundacion’s trademark policy. That said, Fundacion PostgreSQL did go about their actions in an incorrect way. There should have been an open discussion and they should have provided PGCAC the opportunity to resolve the trademark issues on their own. It is also true that while I believe PGEU and PGCAC believe they are protecting the community, if they were interested in positive community growth and collaboration, they would not be taking the approach they currently are. The current path has far reaching implications that PGEU and PGCAC do not see.


Further, the PostgreSQL Community Association of Canada and Fundacion PostgreSQL have resorted to terrible language in representing what is actually going on within the disagreement. Using language such as, “An attack on our community” or “PostgreSQL attacks the community” is immature at best and at worst an intentional decision to use good faith and mindshare against what is largely just a disagreement that could be solved with an active mediator and a few phone calls. If this disagreement is about the best interest of the PostgreSQL community, shouldn’t that involve discourse, honesty, transparency, and kind communication?

Some facts:


  1. The first appearance of a PostgreSQL trademark outside of Canada wasn’t until 2018.
  2. The trademark PostgreSQL in the European Union was not registered until 2018.
  3. The trademark in Canada was registered in 2003 (filed in 1999).
  4. The trademark in Canada does not accurately represent PostgreSQL as the services it was registered under are:

(1) Internet consulting.

(2) Internet presence provider- DNS hosting.

(3) Commercial internet support for database applications development and implementation including the ability to host internet domains (as an internet service provider) and provide a wide range of web site development, programming and information technology services, namely computer software architecture, design and/or development services.

(4) Computer hardware sales and service.

The solution

The solution to the whole problem is simple; a single contract that states:

  1. That the term PostgreSQL is trademarked by the PostgreSQL Community Association of Canada
  2. That the Fundacion PostgreSQL relinquishes all property and rights to the mark PostgreSQL held in Spain and assigns them to the PostgreSQL Community Association of Canada
  3. The PostgreSQL Community Association of Canada forgoes any punitive damages or secondary costs
  4. That the Fundacion PostgreSQL forgoes any punitive damages or secondary costs

The contract should not contain language in regards to future potential filings that involve but are not exclusive to the word Postgres or PostgreSQL. There are already a number of filings worldwide that use Postgres or PostgreSQL as part of an overall mark inclusively such as Postgres Pro, Postgres Plus, Postgres Always On and Postgres Enterprise Manager, all of which are not owned but PGCAC or PGEU.

Why forgo punitive damages or secondary costs

Because it is the right thing to do. Otherwise this whole affair is going to end up costing one entity or another way too much money for no purpose. There is no clear distinction on who would legally win, and in either situation the main sufferers are the PostgreSQL community. Let’s have the parties show an act of kindness for the betterment of everyone involved.

The events are held as a larger meetup style event with networking opportunities and up to 4 presentations. The current agenda for the latest PGConf Mini: NYC is:
 
Agenda: 
 
• 6:30 - 7:00: Jonathan Katz, (TBD), Postgresql Contributor and PGConf Chair Emeritus

Efficiently and Safely Propagate Data Changes Without Triggers!

 

Prior to PostgreSQL 9.4, the primary way to distribute data-driven changes across multiple tables was to use triggers. While triggers guarantee that these changes will be propagated, they can have a significant impact application performance, both technically and with development time (see: "debugging"). PostgreSQL 9.4 introduced logical decoding, which provides a way to stream all changes in a database to a consumer. Using a logical decoder, you can read all changes that are made in a table into your programming language of choice to perform many tasks: cache invalidation, data propagation, submitting changes to remote services, and more. Many PostgreSQL drivers, such as psycopg2 and JDBC support the logical replication protocol, which lets you easily stream your database changes to be manipulated using your favorite programming language. This talk will demonstrate how you can setup logical decoding for your application, look at architecture strategies for working with a logical decoder, and look at a case-study that shows how using logical decoding led to a big performance boost over a similar trigger-based system.
 
• 7:00 - 7:30:  Kevin Jernigan, Senior Product Manager, Amazon
Technical Architecture of Postgres Aurora 
 
Amazon Aurora is a cloud-optimized relational database that combines the speed and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. The recently announced PostgreSQL-compatibility, together with the original MySQL compatibility, are perfect for new application development and for migrations from overpriced, restrictive commercial databases. In this session, we’ll do a deep dive into the new architectural model and distributed systems techniques behind Amazon Aurora, discuss best practices and configurations, look at migration options and share customer experience from the field. 
 
• 7:30 - 8:20: Joshua (JD) Drake POSTPONED due to flight cancellation)
The Power of Postgres Replication, Postgres Expert - Lead Consultant Command Prompt, Inc and Co-Chair PGConf!
 
With PostgreSQL v10 a new replication engine has come to town. Let's explore Postgres Logical Replication, how to use it, optimize it and let it best fit in with your organization. We will also discuss its interactions with external tools as well as Binary Replication and features such as Hot Standby.
