I thought about that, but it pushes you right back to having to do a
join with pg_namespace, which certainly doesn't increase your level of
abstraction from the system catalogs.

That would respond to the abstraction concern in a more complete
fashion. I thought about that one too, but felt that the ability to
look at the whole pg_class row (and not only check existence) had some
value. Also, I've seen people doing things like... where relname LIKE 'pattern' and ...
which still works with the namespace OID function but would not work
with a does_temp_table_exist() function. I wouldn't object to doing
both this and the OID function, though. Do you have a proposal for
the exact spelling of the exists() function?
