Dear readers,

Now, pg_typeof is an alternative but that only goes so far:
it requires laboriously constructing an array on the right
hand side for the above use case, along the lines of:

        select pg_typeof('a'::text) = any(ARRAY[pg_typeof(''::text), 
pg_typeof(''::name)]);

Is there anything obvious I am missing for easily
resurrecting the above "is of" use ?

Actually it can be done as:

select pg_typeof('test'::text) in ('text'::regtype, 'varchar'::regtype);
 ?column?
----------
 t

select pg_typeof(1::int) in ('text'::regtype, 'varchar'::regtype);
 ?column?
----------
 f

Thanks,
Karsten
