Normally vacuum full is NOT required on a regular basis. However, if
you did something like creation 100M tables and then dropped them, or
did it one at a time real fast, you could outrun your autovacuum
daemons and get bloat in the pg catalog tables.

Just offering a possibility for why a connection might be taking a
long time. There's plenty of other possibilities I'm sure.
