Hi,
Looking at this:
http://www.postgresql.org/docs/9.0/interactive/plperl-under-the-hood.html
Specifically, the "known limitations" part, I see it says:
When a session ends normally, not due to a fatal error,
any END blocks that have been defined are executed.
Currently no other actions are performed. Specifically,
file handles are not automatically flushed and objects are
not automatically destroyed."
So I wondered what implications that has for stored procedures that
create objects? Will the following code cause a memory leak if called
many times, due to the $big object never being destroyed?
CREATE FUNCTION foobar() RETURNS trigger AS $$
use Big::Module;
my $big = Big::Module->new;
$$ LANGUAGE plperlu
Perhaps I should test first and email later..
I couldn't see any memory leaking at all in some quick experimentation
(on pg 8.4.5).
