Sure! pgsql-general would work, too, but here is fine.

Meaning what? Could you give that in MB, GB, or TB? What is out
of control about it?

We need more information, especially PostgreSQL version number.

I can't find this error, as you have shown it, in current sources --
so I can't check on what could cause it. Please double-check that
it matches *exactly* with the message you received, and with a
version number we should be able to track that down. Oh, and that
last part of the message probably came from the OS, so knowing
exactly what that is might help.

The error is character for character exact.
