I know TCL and probably Python and others can work with a record as a
trigger function. But TCL doesn't seem to accept a record as an
argument. Can any of the other languages that could also accomplish
this function? Or some other way? Thanks.
A PL that can accept composite types (such as plpythonu) should be able to do this.
OK, python is new to me, so I'm trying to dig into it. I installed it, and tried declaring a function:
CREATE OR REPLACE FUNCTION ebh_transaction_assemble( varchar, record ) RETURNS varchar AS $$...
but got the same error:
ERROR: PL/Python functions cannot accept type record
Is there some other way I should be specifying this? Or do I need a more recent version of Postgres (I'm on 9.2) to do this? Thanks.
