The array type for a base type is automatically created by CREATE TYPE. So the type is already there. What you are (possibly) doing is constructing a value of that array type. But then the OIDs of all the types involved don't change, and you can use the standard functions to look up the types of your arguments and the associated array types. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
