it in mind; since you'll likely see the same variance on production. If you're doing it for your own general learning, then it might still be worth it, but it's hardly an idea setup for that kind of thing. -- PT -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

ssment might be correct. But he hasn't provided enough information to be sure of that. Regardless, lots of "idle in transaction" connections that stick around a long time is a clear sign of application bugs. If they're not the cause of his immediate problem, they will be the cause of problems at some point, so he might as well track them down and fix them. -- PT -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

omplain about database "errors" once you enable that, as connections will get killed and cause errors on the application.

ong that it can't keep up. In theory, setting it too low can cause autovaccum to have a negative performance impact, but I've never seen that happen on modern hardware. But that's all speculation until you know how frequently autovacuum runs on that table and how long it takes to d
