Use EXECUTE sql_string, see http://www.postgresql.org/docs/8.4/interactive/plpgsql-control-structures.html For instance, simple example, untested: create function foo (my_string) returns setof record as $$ declare sql text; begin sql:='SELECT * FROM my_table WHERE id IN (' || $1 || ')'; return query execute sql; end; The variable sql contains the whole query, and then execute that.
