Aggro napsal(a):
I think all information is collected and they are
used for all pg_dump run. It
does not make sense to free them. See line 725.

But is the memory freed at some point? E.g. when
program shuts down? If it is not freed ever, then it
is a memory leak. I'm interested in this, because
either you have a memory leak or these is a bug in
another application called cppcheck which claims that
you have a memory leak. But if it is too difficult to
find out, I won't bother you about this anymore as it
is most likely a minor issue if even that.
Keep in mind that onetime allocated local memory is not reclaimed to OS until
process finished. See sbrk(2) It does not make sense to free memory at the end
(in pg_dump) because it does not have any effect on available memory in OS and
OS clean it soon anyway. I agree that from general point of view it is good to
release unused memory, because process can reuse it. But when you know what you
do then you can break a rule.
