Hello,
we have a strange problem with autovacuum. We have three workers, but
usually only one works and two are waiting as they are all trying to
process table pg_shdepend which is shared between all databases.
We have two clusters, both have a few thousands of databases. Because of
this problem the autovacuum process can't keep up and the planner uses
old data causing large impact on the performance.
Is there a way to prevent this behaviour, please?
With regards
Ondřej Světlík
