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

Hummmmm
We build in 64bit and 32bit.

It looks like configure does figure out that LARGE_FILES is required, only in 32bit.
No need in 64bit.


 # grep LARGE_FILES postgresql-11beta1-1.spec.res_20180530_101845
checking for CFLAGS recommended by Perl... -D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=-1 -qnoansialias -qlanglvl=extc99 -DUSE_NATIVE_DLOPEN -DNEED_PTHREAD_INIT -maix32 -D_LARGE_FILES
checking for _LARGE_FILES value needed for large files... 1

This is for 32bit only.



32bit and 64bit:
# find . -name "Makefile*" | xargs grep LARGE_FILE
#

64bit:
# grep LARGE_FILES config.log
#

32bit:
# grep LARGE_FILES */config.log
32bit/config.log:configure:9421: result: -D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=-1 -qnoansialias -qlanglvl=extc99 -DUSE_NATIVE_DLOPEN -DNEED_PTHREAD_INIT -maix32 -D_LARGE_FILES
32bit/config.log:configure:14471: checking for _LARGE_FILES value needed for large files

32bit/config.log:#define _LARGE_FILES 1



# find . -name "*.h" | xargs grep LARGE_FILE

However, in 32bit, though there is:
   #define _LARGE_FILES 1
in file :
   src/include/pg_config.h
I had to add it at the beg of file by means of a patch to several files:
src/pl/plpython/plpy_cursorobject.c
src/pl/plpython/plpy_elog.c
src/pl/plpython/plpy_exec.c
src/pl/plpython/plpy_main.c
src/pl/plpython/plpy_planobject.c
src/pl/plpython/plpy_plpymodule.c
src/pl/plpython/plpy_procedure.c
src/pl/plpython/plpy_resultobject.c
src/pl/plpython/plpy_spi.c
src/pl/plpython/plpy_subxactobject.c
src/pl/plpython/plpy_typeio.c
src/pl/plpython/plpy_util.c
contrib/hstore_plpython/hstore_plpython.c
contrib/ltree_plpython/ltree_plpython.c
contrib/jsonb_plpython/jsonb_plpython.c
src/common/file_perm.c

All involve plpython. Maybe we have something wrong there and my patch is a work-around.
However, my work-around works perfectly for v10.4 and v9.6.9, built in the exact same environment, but not for v11beta1 .

> For files: contrib/jsonb_plpython/jsonb_plpython.c and src/common/file_perm.c , I had to use #define _LARGE_FILES 1 like I did for 14 older files. That deals with lseek() and lseek64() definitions.

I'm not following this. Doesn't configure manage to figure out that
_LARGE_FILES=1 is needed? It certainly tries to.
