RE:PostgreSQL 11 beta1 on AIX 7.2 : 2 failures in 32bit mode

Hi Tom,

Yes, there is something strange with _LARGE_FILES in 32bit.
However, that exists too with version 10.4 and 9.6.9 , and tests are 100% OK.
So, it seems that something new appears within v11

v11beta1 brings new json files. Either these files reveal some issue on AIX 32bit or they contain code that is not compatible with AIX environment and some change should be applied...

Cordialement,

Tony Reix

This is surely not what's intended. It seems like plpython is messing
things up somehow, probably through an #include-ordering error, but
I don't see the exact problem offhand.

I wondered why the existing 32-bit AIX buildfarm machines aren't showing
problems, but looking closer at them, they are manually forcing
_LARGE_FILES, which probably is masking things:

'config_env' => {
'CC' => 'wrap-gcc -D_THREAD_SAFE=1 -D_LARGE_FILES=1 -maix32',

Noah, why'd you do that, and would you be willing to remove it? IMO
Postgres should work without that.
