Ok, that makes sense. Attempting the below, but receiving this error:

./configure --without-readline --with-includes=/usr/lib --with-openssl

checking for CRYPTO_new_ex_data in -lcrypto... no
configure: error: library 'crypto' is required for OpenSSL

You don’t have crypto installed on your machine.

Try something like 

Redhat / Centos / Fedora : sudo yum install openssl-devel 
Ubuntu / Debian : sudo apt-get install libssl-dev


[postgres@servername postgresql-14.2]$ ls -lhrt /usr/lib/*crypt*

Our RHEL 7.9 installation comes with PostgreSQL 9.2 installed which I know has been desupported. We installed 14.2 in a non-default location and observe this unusual behavior:

Any ideas of why I'm encountering this issue?

Looks like you neglected to build psql with OpenSSL support, and the server is insisting on having an SSL connection.
