You can do it via hstore in 9.0+...just be aware it is slower than the row constructor method. See the example below -- note CREATE EXTENSION is a 9.1 feature -- to do it in 9.0 you have to install the contrib script manually. postgres=# create extension hstore; WARNING: => is deprecated as an operator name DETAIL: This name may be disallowed altogether in future versions of PostgreSQL. CREATE EXTENSION postgres=# create type t as (a int, b text); CREATE TYPE postgres=# select populate_record(null::t, 'b=>9, a=>2'); populate_record ----------------- (2,9) merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
