Hmm, this would have been a great help to me not long ago, so I'd say it
would be nice to have.
About the exact form we'd give the feature: maybe write each
allocation/freeing to a per-backend file, say /tmp/pgmem.<pid>. Also
memory context creation, destruction, reset. Having the __FILE__ and
__LINE__ on each operation would be a good tracing tool as well. Then
it's easy to write Perl tools to find specific problems.
