At the Seattle PostgreSQL User Group meetup this past Tuesday, we got onto the topic of invalid pages in PostgreSQL.

I’m looking forward to the Seattle PostgreSQL User Group meetup this Thursday (June 20, 2019) at 5:30pm! We’re going to get an early sneak peek at what’s coming later this year in PostgreSQL’s next major release. The current velocity of development in this open source community is staggering and this is an exciting and valuable … Continue reading
PostgresConf 2019 in New York City is a wrap! Now that I’ve had a few days to recover a little brain capacity, I think I’m ready to attempt a summary. I love conferences for the learning opportunities… inside of sessions and also outside of them. Being the largest PostgreSQL-centered conference in the United States, PostgresConf … Continue reading
