Well, that's a simple test case all right :)

Without knowing more, my guess is that it is AIX-specific, and specific
to your version and/or compiler. We have (had?) at least a few other
active developers on AIX, and afaik they are not seeing this on their
installations. I'll guess that they are not as current as you are on
versions of OS and compilers.

You say that AIX already defined int32, etc. Are those definitions
exactly compatible with those in the Postgres sources? If so, then
perhaps you can submit patches which do a conditional definition in the
Postgres code (e.g. #ifndef int32...).

Have you compiled with assert checking turned on? Have you compiled
without optimizations (-O0)? Do other operations on the database seem to
work, such as table creation or row insertion? I'll be interested in
seeing what you find when using gcc.
