The documentation says "It is currently not allowed," which suggests
that perhaps it could be allowed in a future version.  Don't expect
to see it in 8.1, however, since that version is long past feature
freeze.  I don't recall how much, if any, discussion there was on
this; search the pgsql-hackers archives to find out.

Could you tell us more about what you're doing?  Maybe there's
another way to achieve it.
