Just tried to build Postgres 17 on AIX

Apparently I missed the memo that support for AIX was being dropped in Postgres 17.

When attempting to build 17.1 on AIX today I got this message:

checking build system type... powerpc-ibm-aix7.1.3.0

configure: error:

*******************************************************************

PostgreSQL has apparently not been ported to your platform yet.

To try a manual configuration, look into the src/template directory

for a similar platform and use the '--with-template=' option.

Please also contact <pgsql-bugs@lists.postgresql.org> to see about

rectifying this.  Include the above 'checking host system type...'

line.

Is manual configuration an option or are we just out of luck as far as Postgres 17 on AIX?

Thanks, Mark
