I think the closest approximation of disabling autovacuum on a per
database basis is to connect to the database in question and perform:
update pg_autovacuum set enabled = 'false';
This will prevent autovacuum from vacuuming or analyzing any of the
tables in the database, but will still check for XID wraparound.
Problem with that is any time you add a table you'd need to re-run that
command. Wouldn't be so bad if we had DDL triggers, but...
Probably a dumb comment, but can you set a default value for the enabled
column?
