This was fixed in 8.1.5 ... or at least the only known cause was fixed.

backend/utils/cache/syscache.c, include/utils/catcache.h: Fix
SysCacheGetAttr() to handle the case where the specified syscache
has not been initialized yet. This can happen because there are
code paths that call SysCacheGetAttr() on a tuple originally
fetched from a different syscache (hopefully on the same catalog)
than the one specified in the call. It doesn't seem useful or
robust to try to prevent that from happening, so just improve the
function to cope instead. Per bug#2678 from Jeff Trout. The
specific example shown by Jeff is new in 8.1, but to be on the safe
side I'm backpatching 8.0 as well. We could patch 7.x similarly
but I think that's probably overkill, given the lack of evidence of
old bugs of this ilk.
