Re: Vacuum Full Analyze Stalled

On the linux box check if any application left a "idle in transaction" backend
around.
just
ps -ef | grep transaction

if that shows any postgres process then you most likely found the culprit.
An application that's still running can have a bug that starts a transaction
which never finishes for some reason (commit or rollback it never called).
I had a couple of those errors in my app - always leading to a stuck vacuum
full. If that's the case just kill the backend in question and the vauum will
continue. Don't kill -9 it!!
After that try to figure out what caused the application not to commit or
rollback a transaction. It's usually an error handler of some sort.

just an idea.
