User-defined types
Anyone know of a quick and dirty query that can retrieve the various type
definitions ? I am looking to retrieve the schema-equivalent representation
of a custom (user-defined) types.

Invoking "pg_dump -s" is by far the most future-proof approach.

I figured it out....
BTW: I was thinking more along the lines of:
SELECT PT.*, PA.* FROM pg_attribute PA
JOIN pg_type PT ON PA.attrelid = PT.typrelid
JOIN pg_class PC ON PC.oid = PA.attrelid
WHERE PT.typnamespace = 2200 AND PA.attnum > 0 AND PC.relkind IN ('r', 'c',
'v');
Perhaps this should be made into a view in the information_schema.....

It seems like the COLUMN_UDT_USAGE view ought to handle this ...
except perhaps that COLUMN_UDT_USAGE for some reason substitutes the
underlying type if the column type is a domain. I can't see the
justification for that --- Peter, what part of the spec led you to do
it that way? There is probably more than one way to define the spec's
notion of "user-defined types" in terms of Postgres notions, but I
don't see where you got this particular definition.
