Oh? The current documentation still defines the variable thusly:
Specifies the minimum delay between autovacuum runs on any given
database. In each round the daemon examines the database and
issues VACUUM and ANALYZE commands as needed for tables in that
database.
I suppose the use of "minimum" means that this is not technically
incorrect, but it's sure not very helpful if there is some other
rule involved that causes it to not behave as I said. (And if there
is some other rule, what is that?) Please improve the docs.
