I just played around a bit on my laptop running 10.4, and was able to
compile a universal version of libpq, pg_dum and pg_config.
What I did was:
1) export CFLAGS="-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk/"
2) export LDFLAGS="-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk/"
3) ./configure
4) cd src/interfaces/libpq; make
5) cd src/backend; make ../../src/include/parser/parse.h
6) src/bin/pg_config; make
7) src/bin/pg_dump; make
The only problem I can see is that ld isn't able to generate universal binaries - it
can read them, but always strips all but one arch when generating output...
The apple gcc, however supports multiple archs just fine, and even knows that it
has to call ld repeatedly, and then merge the resuting files...
So, to build a complete postgres distribution, I believe one would have to somehow tell
configure to use gcc instead ld (if it doesn't already do that).
But for building pgadmin3, the parts I built above are sufficient - in fact, those
are exactly the parts of postgres that my buildaemon-postgres-update script builds ;-)
(Don't ask me why step (5) is necessary... It was quite a long time ago that I wrote
this script... ;-) ).
