Okay, then it is a postmaster leak. The backends are started by fork
from the postmaster, so they'd inherit whatever data memory size the
postmaster currently has.

Not possible for a backend to affect the postmaster like that, AFAICS.
I think it's just a garden-variety memory leak in some postmaster
operation.
Since this isn't being reported by other folks, either there's a
system-specific problem or you are using a postmaster feature that's not
widely used. RedHat 6.2 is pretty common so we can probably eliminate
system-specific issues. Which authentication method(s) do you use?
(If you could send your whole pg_hba.conf file, that might be useful to
look at.)
