I have been a PostgreSQL administrator since 2002 and have worked for Fred Hutchinson Cancer Research Center for the last 10+ years. Within Fred Hutch, I work for the largest group called SCHARP, Statistical Center for HIV/AIDS Research and Prevention.
In 2010 I started SeaPUG, Seattle Postgres Users Group, at the request of Josh Drake. I present at least half the presentations there every year. I have also discovered several PostgreSQL: bugs which have been fixed, some of them affected every version of PostgreSQL. Bug numbers: 7553, 8173, 8257, 8291. Bug 8545, is fixed PostgreSQL 11. I started the PostgreSQL track at LinuxFest Northwest in 2014 after my GIS presentation in 2013 was standing room only. In 2017 I got a booth at the SeaGL, Seattle GNU Linux, conference with the idea of having a booth there in 2018 along with also doing a PostgreSQL presentation at the conference. In 2017 I started presenting at various PostgresConf Conferences.
I host the Seattle Postgres Users Group where I give many of the presentations. I have many of the presentations posted at Lloyd's Presentations
