Ok,
So this took a while, but here's your test case.....
Turns out to be quite small actually ;)
create table t1 (id int);
CREATE FUNCTION tr_t1_after_iud()
RETURNS trigger
LANGUAGE 'plpgsql'
VOLATILE
STRICT
SECURITY INVOKER
AS 'DECLARE
BEGIN
RAISE NOTICE ''%'', ROW(NEW.*);
SELECT 1/0;
RETURN NEW;
END;';
CREATE TRIGGER t1_after AFTER INSERT OR UPDATE OR DELETE ON t1 FOR EACH ROW
EXECUTE PROCEDURE tr_t1_after_iud();
begin;
savepoint s1;
INSERT INTO t1 values (1);
=> this will result in the following:
db=# INSERT INTO t1 values (1);
NOTICE: (1)
WARNING: AbortSubTransaction while in ABORT state
WARNING: did not find subXID 77063 in MyProc
ERROR: division by zero
CONTEXT: SQL statement "SELECT 1/0"
PL/pgSQL function "tr_t1_after_iud" line 4 at SQL statement
ERROR: tupdesc reference 0x7ffe74f24ad0 is not owned by resource owner
SubTransaction
=> mind the fact that the savepoint is 'needed', without it there will be no
problem
=> in my reallife example, this resulted in a "PANIC: ERRORDATA_STACK_SIZE
exceeded", I cannot reproduce that, but as you stated earlier, this might just
be collateral damage, which I'll be able to easily confirm once the problem
above has been fixed.
=> cleanup:
rollback;
drop table t1;
drop function tr_t1_after_iud();
=> to avoid possible confusion
db=# select version();
version
