FWIW, that's exactly what we currently do in DBD::Pg to generate an up to
date list of types:

## $file = "pg_type.h"
open(F, $file) or die qq{Could not open file "$file": $!\n};
my %oid;
my $maxlen = 1;
while(<F>) {
next unless /^#define\s+([A-Z0-9_]*OID)\s+(\d+)/o;
$oid{$1} = $2;
length($1) > $maxlen and $maxlen = length($1);
}
close(F);

We actually go on from there to build a bunch of custom C structs. The maxlen
is simply there to make our final "types.c" line up pretty.

Installing it at the top-level sounds good, although I don't think
we'd see a need to switch to it since we already parse pg_types.h ourselves. ;)
