Ah, so the problem really boils down to funny naming conventions.
If they use ".a" for both shared and static libraries, how does anyone
tell the difference?

I wonder whether we ought to suppress building (or at least installing)
our .a libraries at all on AIX. Adding -btrl to LDFLAGS would help
within the context of our own build, but external clients that link
to libpq without saying that are going to get undesirable results.
I think there's a reasonable argument that by installing a .a file that
isn't a shared library, we are violating the platform's conventions.

Sounds that way, but that'll only help for psql and other stuff built
within our build. Could you try this against CVS tip:
* add -brtl to LDFLAGS in the template
* Remove the AIX-specific hack on $(libpq) at lines 349-354 of
src/Makefile.global.in
* see if it configures and builds
