project I am working on (Recall - a distributed, fault-tolerant,
replicated, storage framework @ http://www.fault-tolerant.org).
Recall is written in C++.  I need to include the postgres headers and
there are some problems when including the headers w/C++.

Attached is a patch generated from postgres/src that fixes my problems.
I was hoping to get this into the main source.  It's very small (2k) and
3 files are changed: backend/utils/fmgr/fmgr.c,
backend/utils/Gen_fmgrtab.sh.in, and include/access/tupdesc.h.

In C++, you get a multiply defined symbol because the variable
(FmgrInfo *fmgr_pl_finfo) is defined in the header (the patch moves it
to the .c file).  The other problem in tupdesc.h is the use of typeid
is a problem in c++ (I renamed it to oidtypeid).

Thanks,
