I don't recall all the details, but some plpgsql constructs would use
memory that wouldn't be reclaimed until function exit.  So if you
had a long-running loop inside a function, you could see memory
problems.

I'm not convinced that 7.2 is *entirely* free of such problems, but it's
a lot better than 7.1 was.
