I think we should work on generating a lot of func.sgml.  Particularly the
signature etc should just come from pg_proc.dat, it's pointlessly painful to
generate that by hand. And for a lot of the functions we should probably move
the existing func.sgml comments to the description in pg_proc.dat.

I suspect that we can't just generate all the documentation from pg_proc,
because of xrefs etc.  Although perhaps we could just strip those out for
pg_proc.

We'd need to add some more metadata to pg_proc, for grouping kinds of
functions together. But that seems doable.
