PostgreSQL version: 14.12
Operating system:   SUSE 15 SP 4
Description:

Hi,
This is more of an inquiry than a bug report, but lately I have been trying
to install PostgreSQL 14.12 on a SUSE 15.4 machine and ran into an error:

bin/postgres: libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required
by /opt/mstr/install/Repository/postgres14/lib/libicuuc.so.73)

Basically, my understanding is that PostgreSQL 14.12 requires some ICU
libraries that are compiled with higher version of glibc than SUSE 15.4's
default one. I noticed this issue on SUSE 15 SP 5 as well. Problem is, I
have a client who is on SUSE 15.4 and is not willing to install SP 6 (but
may consider SP 5), and also doesn't want to upgrade glibc version due to
other concerns. In this case, do you see any other way of making PostgreSQL
14.12 functioning on SUSE 15 SP 4 or 5? Thank you.
