Hello again,
we have another strange problem with autovacuum. The process goes well
until it reaches the table pg_database (in some databases, not all),
then it loops over it forever (until I run vacuum full analyze on that
table, simple vacuum doesn't help):
2016-05-05 17:13:33 CEST 34818LOG: automatic vacuum of table
"somedatabase.pg_catalog.pg_database": index scans: 0
pages: 0 removed, 233 remain
tuples: 0 removed, 5817 remain, 0 are dead but not yet removable
buffer usage: 87 hits, 0 misses, 0 dirtied
And now the same goes for pg_authid. Sorry for spamming, I hope this is the
last one.
These are all shared catalogs. There are others, so you may still see
more. We got another report for pg_database
https://www.postgresql.org/message-id/A9D40BB7-CFD6-46AF-A0A1-249F04878A2A%40amazon.com
so I suppose there really is a bug. I don't know what's going on there.
Let me know if I can help trace the cause.
With regards
Ondřej
