Tom Lane 4a1b05caa5 Restore AIX support. ... The concerns that led us to remove AIX support in commit 0b16bb877 have now been alleviated: 1. IBM has stepped forward to provide support, including buildfarm animal(s). 2. AIX 7.2 and later seem to be fine with large pg_attribute_aligned requirements. Since 7.1 is now EOL anyway, we can just cease to support it. 3. Tossing xlc support overboard seems okay as well. It's a bit sad to drop one of the few remaining non-gcc-alike compilers, but working around xlc's bugs and idiosyncrasies doesn't seem justified by the theoretical portability benefits. 4. Likewise, we can stop supporting 32-bit AIX builds. This is not so much about whether we could build such executables as that they're too much of a pain to manage in the field, due to limited address space available for dynamic library loading. 5. We hit on a way to manage catalog column alignment that doesn't require continuing developer effort (see commit ecae09725). Hence, this commit reverts 0b16bb877 and some follow-on commits such as e6bb491bf, except for not putting back XLC support nor the changes related to catalog column alignment. Some other notable changes from the way things were in v16: Prefer unnamed POSIX semaphores on AIX, rather than the default choice of SysV semaphores. Include /opt/freeware/lib in -Wl,-blibpath, even when it is not mentioned anywhere in LDFLAGS. Remove platform-specific adjustment of MEMSET_LOOP_LIMIT; maybe that's still the right thing, but it really ought to be re-tested. Silence compiler warnings related to getpeereid(), wcstombs_l(), and PAM conversation procs. Accept "libpythonXXX.a" as an okay name for the Python shared library (but only on AIX!).
