Okay, I still have not got it installed. So far, I have put about 10hrs into this.
I am now getting a “collate.linux.utf8” fail during the “regression test” part of the compiling-build of postgresql14. The detailed error is posted below from this file in my home folder. (~/.cache/yay/postgresql14/src/postgresql-14.2/src/test/regress/expected/collate.linux.utf8.out)
/*
* This test is for Linux/glibc systems and assumes that a full set of

I know this is an issue with my setup not the package from AUR. I just don’t know how to resolve it.
All my locals in /etc/locale.conf are set correctly.

LC_IDENTIFICATION=en_US.UTF-8
LC_MEASUREMENT=en_US.UTF-8

LC_NUMERIC=en_US.UTF-8
LC_PAPER=en_US.UTF-8
LC_TELEPHONE=en_US.UTF-8
LC_TIME=en_US.UTF-8
LC_COLLATE=en_US.UTF-8
LC_CTYPE=en_US.UTF-8
Any ideas?
Thanks again!
