For 7.0.x, Alpha builds require patches, which would probably help you
also. Tom Lane has rewritten the function manager (fmgr) interface, and
these patches are not necessary in the current development tree. You
might want to try that since we are probably approaching the beta test
period.

This is probably a symptom of the unpatched 64-bit build...
