Re: to_typemod(type_name) information function

Hi,

the following patch allows to retrieve the typemod. Without this patch,
it does not seem to be possible to generate the first column.

SELECT format_type(to_regtype(t), pg_to_typemod(t)),
format_type(to_regtype(t), NULL)
FROM (VALUES
('INTERVAL SECOND (5)'),
('Varchar(17)'),
('timestamptz (2)')) AS x(t);
format_type | format_type
-----------------------------+--------------------------
interval second(5) | interval
character varying(17) | character varying
timestamp(2) with time zone | timestamp with time zone

I did not find any advice on how to choose a new OID for pg_proc.

Best,
Sophie
