So, for my 2c, I'm on the other side of this, personally.  We have
memory contexts for more-or-less exactly this issue.  It's one of the
great things about PG- it's resiliant and very unlikely to have large or
bad memory leaks in general, much of which can, imv, be attributed to
our use of memory contexts.
