RE: AIX support

Hi Tom and community members,

Please find attached the patch (See: v4-0001-Add-AIX-support-for-Postgresql-using-meson-build-.patch)

You will need to git apply your patch and then this patch.

I had missed out a few things like the die message change in the .pl file in the v3 of this patch.

Also, the export OBJECT_MODE=64 flag is tentatively only needed.

I maintain meson in AIX and have raised a PR (link below) to eliminate the need to do the same. Once merged will update meson in AIX and we will no longer need to export the same.

https://github.com/mesonbuild/meson/pull/15516

So this puts AIX in sync with other targets and we can also now just do meson setup build && meson compile -C build to build the project.

Have a nice day ahead.

Thanks and regards,
Aditya.

Thank you for the push. We have updated our branch. And this patch is made after the update.

I have taken care of the same. Please see now and let me know.
