Hey Hackers,
I just had reason to want the way that format_type converts type names (e.g., varchar => character varying) in pgTAP,
butdidn't want the namespace qualification (used by format_type() when the type in question is not visible). I figured
outthat I could get that conversion by simply casting the OID argument to regtype, but then to get the typmod, I still
haveto use format_type() like so:
CREATE OR REPLACE FUNCTION display_type ( OID, INTEGER ) RETURNS TEXT AS $$ SELECT $1::regtype || COALESCE(
substring(pg_catalog.format_type($1, $2), '[(][^)]+[)]$'), '') $$ LANGUAGE SQL;
Is there a saner way to do it than this? That is, is there a better way to get the typmod than by munging the value
returnedby format_type()?
Thanks,
David
