as new know plpgsql has special cache which remember too long (event
non-existing tables (i mean old oid)) so i suggest to create same function
only in plpgsql which would clear this cache, or sth like this ?
for ie, where i drop table i would do plpgsql_clear_cache ();
and when i will create one more time table with this same name plpgsql
will not remeber wrong oid
possible ?
