But if they restore a dump made with pg_dump or pg_dumpall, they'll
get the old catalog entries sans STRICT, no?  People might rebuild
the module when they upgrade, but they might not think to drop and
recreate the functions since the definitions are already in the
dump.  I suppose the Release Notes could mention that recreating
the functions is required; it could also show the SQL statements
necessary to update pg_proc so a drop/recreate wouldn't be necessary.
