Depending on what you mean by "successfully executed," see "Obtaining
the Result Status" or "Trapping Errors" in the PL/pgSQL documentation
(error trapping is available in 8.0 and later).

OK, this question got me wondering: is there a way to determine, in a
function/stored procedure, the number of rows that were
inserted/updated/deleted?
For example, the following does NOT work but shows what I am trying to
achieve:
CREATE OR REPLACE FUNCTION "public"."test_fn" () RETURNS VOID AS
'
DECLARE
mycount INTEGER;
BEGIN
-- This assignment will not work be I want something like it
-- so I can count the number of records updated.
mycount := EXECUTE
''update mytable '' ||
''mycolumn = 1 '' ||
''WHERE '' ||
'' mycolumn = 2 ''
;
RAISE NOTICE ''count = %'', mycount;
RETURN;
END;
'
LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
I could not find any documentation about getting the count of updates but
when you run the update by itself, PostgreSQL reports the number of records
updated so I have to believe the information is available somewhere.
Thanks,
Aaron

Look for the section entitled "36.6.6. Obtaining the Result Status" on
the link that Michael Fuhr supplied (above). Is that what you are
looking for?

Ah yes, I missed the part on ROW_COUNT . That should do it.
