Thread: creating a dump

creating a dump

From

Hello,

I try to dump my databases using pg_dumpall or pg_dump and I get the following error:

\connect bic postgres
getAggregates(): SELECT failed.  Explanation from backend: 'ERROR:  Attribute 'aggtransfn1' not found
'.
pg_dump failed on bic, exiting


I tried to fiddle around with the privileges, granted public access to the database to no avail.

Any clues why this happens?

BTW, I would like a cron job to periodically dump out the data in a restorable form.

Best Regards,

Hegyvari Krisztian

I think you are trying to use a 7.0 or older pg_dump against a 7.1 or
newer database.  Or maybe it was 7.2 where we changed the layout of
pg_aggregate.  Anyway, this is a version skew problem.

(Newer versions of pg_dump do complain if the server version isn't one
they recognize, btw.  But you are invoking an old one :-()
