Call pgstat_drop_database during DROP DATABASE, so that any stats file

Browse Source 
entries for the victim database go away sooner rather than later.  We already
did the equivalent thing at the per-relation level, not sure why it's not
been done for whole databases.  With this change, pgstat_vacuum_tabstat
should usually not find anything to do; though we still need it as a backstop
in case DROPDB or TABPURGE messages get lost under load.
