pgsql: Fix autovacuum's database sorting. - Mailing list pgsql-committers

Fix autovacuum's database sorting.

When db_comparator() was updated to use pg_cmp_s32(), the arguments
were listed in the wrong order.  This caused autovacuum to sort the
databases by their scores in ascending order instead of descending
order.  To fix, swap the arguments to pg_cmp_s32().

Oversight in commit 3b42bdb471.
