Here are two patches. The guc_and_tablefunc patch addresses the two
changes mentioned above, and also adds a new function to the tablefunc
API. The tablefunc API change adds the following function:
* Oid foidGetTypeId(Oid foid) - Get a function's typeid given the
* function Oid. Use this together with TypeGetTupleDesc() to get a
* TupleDesc which is derived from the function's declared return type.
In the next post I'll send the contrib/tablefunc patch, which
illustrates the usage of this new function. Also attached is a doc patch
for this change. The doc patch also adds a function that I failed to
document previously.
