Philip Warner (pjw@rhyme.com.au) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
vacuum dies when called from plpgsql after large delete
Long Description
Large table (> 13M rows), nightly job deletes approx 0.5M rows, then does a vacuum. It looks like the vacuum part is
failing.Subsequently going into psql and issuing a vaccum command works. The following is the log from the time of the
crash:
