Are there any other details I can provide to help diagnose this issue?
It is a production server, so I'd like to rule out the likelihood of
corruption etc if possible. There were about 3400 entries related to
that message yesterday, referencing two tables (pg_statistics and a
user table). The messages haven't reoccurred, and I've run a couple of
cluster-wide vacuum analyzes to see if I could shake anything else
out.
