When we tried on a test server we were seeing issues with =
libcrypto.so.10 and libssl.so.10=20

I know sometimes symlinks are needed but we can't seem to get these to =
work which led to my question of if postgres12 was supported on rhel9.3=20

Presumably you will install the RHEL 9 packages which will be built with =
all of the needed dependencies. If so, you should be fine there.

But beware of collation changes. You will almost certainly need to =
rebuild some indexes afterwards.

Lest you think you will not be affected, see:
