Purpose Built Data Types
at
CHINA 2020 And PGConf.Asia 2020
presented by Jim Mlodgenski
When designing applications, the database schema is usually an afterthought. When the time comes to finally create the tables, developers normally just use a few base data types, like integers, varchars and timestamps, but PostgreSQL can do more. PostgreSQL's architecture allows for easy extension of data types. In this talk, we will explore some of PostgreSQL's purpose built data types that ca...
