Hi list,
I don’t understand the difference between the following syntax :
CREATE FUNCTION "test_check_a_id" () RETURNS opaque AS '
And
CREATE FUNCTION LAST_UPDATED() RETURNS "trigger" AS $$
Especially the difference between opaque and “trigger”.
And the double quotes, seems sometimes used and sometimes not.
Are there any documentation available out there about triggers / functions syntax ?
Many thanks in advance !
Nico
