Обсуждение: How to automatically propagate new/changed database functions from one database to another
We want to implement a mechanism by which if any database function is created or modified in one database, then the same should automatically get done in another (1 or more) database(s).
It seems triggers on system catalogs like pg_proc are not allowed. Is there any way in postgres to do this, by some other way?
Thanks!

We recently upgraded from postgres version 8.2.7 to 8.3.7. The below pl/pgsql test function behaves differently in the 2 versions.
The code of the function is :-
CREATE OR REPLACE FUNCTION "public"."testloop" () RETURNS varchar AS
$body$
BEGIN
FOR idx IN 1..10 LOOP
raise notice 'idx=%', idx;
idx:=idx+1;
END LOOP;
return '';
END;
$body$
LANGUAGE 'plpgsql'
The sql :-
select testloop();
in 8.2.7 returns:-
NOTICE: idx=1
NOTICE: idx=3
NOTICE: idx=5
NOTICE: idx=7
NOTICE: idx=9
But in 8.3.7 returns:-
NOTICE: idx=1
NOTICE: idx=2
NOTICE: idx=3
NOTICE: idx=4
NOTICE: idx=5
NOTICE: idx=6
NOTICE: idx=7
NOTICE: idx=8
NOTICE: idx=9
NOTICE: idx=10
So in 8.3.7, the incrementing of the for-loop variable “idx” is being ignored; that is not the case in 8.2.7. Is this a new feature of 8.3.7 or a bug?
Since a lot of our functions depend on manual altering of for-loop variables, any prompt help/advise/suggestions would be greatly appreciated!
Thanks!
