memory leak with Abort Transaction

Hello!

A background postgres porocess gets larger with Abort Transactions.
Memory seems to leak.
This occurs also on 6.3.2.

You can see it with user aborts:

========================================================================
#!/bin/sh

yes 'begin;
abort;' | psql regression
========================================================================

And with internal aborts:

========================================================================
#!/bin/sh

yes "insert into Room (roomno) values ('000');" | psql regression
========================================================================

Regards
