Hi,
I see that one of the bug fixes in 7.4.3 is:
"Fix temporary memory leak when using non-hashed aggregates (Tom)"
I am still using 7.4.2, and want to find out if I need to upgrade to 7.4.3.
I did not quite understand the bug, or find a way to re-produce this in the
mailist archives.
Can someone point me to the test case which can re-produce this problem.
Thanks a lot in advance,
guna.

Check your locale settings.
IIRC, --enable-locale was not default in 7.2 days, but it is default
(in fact mandatory) now. So it's possible that the 7.2 installation
doesn't have locale support at all and is defaulting to C-locale
behavior. If your 7.2 was built with locale support, then it was
probably initdb'd under a different locale setting than your 7.4 was.
In 7.4 you can just do "show lc_collate" to check, but in 7.2 I think
you have to use pg_controldata (or in a pinch, "strings pg_control")
to find out what locale it's using. regards, tom lane
