I fixed some problems along that line during the 6.5 cycle, and thought
the issue closed.  Perhaps the problem's come back.

Hmm, there must be multiple descriptors open for the same file then?
That's really weird.  Can you obtain a listing of just what is open,
using lsof or some similar tool?  Even better, can you provide a
reproducible test case that will cause descriptor leakage?

Also, exactly what do you mean by "Postgres used up..." --- is this
one backend, or a total across the whole system (if so, how many
backends are we talking about here?).
