Обсуждение: question about information_schema

I'm trying to implement getUDT for the jdbc driver.

It requires the basetype of a type.

If I do create type testint8 as (i int8) and then select typbasetype
from pg_type where typname='testint8' the value is 0?

While I'm asking how can I find all of the user defined types, assuming
that the user is the owner of the cluster. I see that pg_dump can do
this ?

You've created a complex type here, not a domain.  See typtype and 
typrelid for this case.

create domain testint8 as int8;  will do what you were expecting.

IIRC, what pg_dump actually does is look for types that are not in the
pg_catalog schema.  Plus you probably want to exclude composite types
other than "standalone" ones (ie, all those whose associated pg_class
entry has a relkind other than COMPOSITE_TYPE).
