PG Phriday: Constipated Connections
We’ve all had it happen. One day, we run a query or function and we wait for the result. And we wait. And we wait. Eventually, we realize something is wrong and find a DBA and yell at them. “Hey Postgres dude!” we scream. “The database is slow!” Or maybe we can’t even get a connection. Postgres just keeps saying something about too many clients. This application isn’t launching and there are ten managers breathing down our neck and we panic.
