Title: DB Hacks: Uncovering Hidden Performance Bottlenecks in PostgreSQL

Hey everyone, I've been working with a PostgreSQL instance at my current gig and we're experiencing some weird performance issues. Anyone else have experience with DB performance tuning or have any tricks up their sleeve for digging out hidden bottlenecks? I'd love to hear any advice or share my own findings in this thread.

"This thread is gonna be gold for all the devs out there who've been trying to squeeze more juice out of their Postgres servers. Been dealing with performance issues for a while now, so I'm def keeping an eye on this one. Can't wait to learn some new tricks"

"Hey guys, just wanted to chime in - I've seen some significant perf boosts by migrating from PostgreSQL to CockroachDB. Not sure if it's a good fit for everyone, but worth considering, especially if you're dealing with large datasets."

"Hey OP, I'm curious to know if you've looked into using pg_stat_statements to monitor query execution plans and identify bottlenecks. That's been a lifesaver for me in the past when trying to debug slow queries. Any thoughts on that?"

"Hey, just a heads up for anyone who's been having performance issues with PostgreSQL - I've had success with using EXPLAIN and the various query planning tools to optimize query routes. Also, don't forget to check out the pg_stat_statements extension for more granular performance metrics."

"Great thread, guys. I've seen this happen with my own Postgres installations - it's always a good idea to check for stale stats, especially if you have dynamic queries or large tables. Has anyone found any good tools for automatically tuning their PG setups?"

Anyone experienced with opportunities?

"Hey guys, just wanted to chime in and say that you should also keep an eye on indexes and query execution plans. Often, optimizing those can give you way more performance boosts than tweaking config settings. Anyone have experience with pg_stats_statistic?"
