Hello,
I've had a problem during invoking the pg_dump program. I get the
following result:
NOTICE: get_groname: group 2 not found
getTables(): SELECT failed. Explanation from backend: 'pqReadData() --
backend closed the channel unexptectedly
The point is that everything used to work fine, and I don't know actually
when and why this error ocurred.
I did the vacuum a few times but it didn't help. The error occurs also,
when I try to dump a single table - even if it has just been created as a
new one.
What can be the reason and what should I do to make a backup of the
database?
thanks in advance
mark
