The server executables will probably not work, except on the arch you
built on. The client programs might accidentally fail to fail;
I'm not sure whether they contain any dependencies on the arch-specific
values that are extracted by configure. You really need to create
pg_config.h contents that are correct for the specific arch you're
trying to compile for. The last time I tried this, the only good way
to do that was by running configure on the particular architecture.
(Maybe 10.6 has got some cute way around that, but I doubt it.)

Can't speak to SQLite, but I know quite well that mysql has got
essentially the same issues as PG with having arch-specific configure
output. Have you actually tested those universal builds on any arch
except where you built them?
