RPMs from postgresql.org break CentOS/RHEL RPMs

Hi!

I have a system installed where one software is running a database 
using the PostgreSQL 9.2 packages included in the CentOS/RHEL 7 
release. On the side, I am trying to install another software that is 
using the PostgreSQL 12 packages found at download.postgresql.org 
(EL-7-x86_64). However, I am running into problems when both are 
installed at the same time, the postgresql.org ones causes the CentOS 
packages to fail at run-time:

psql: symbol lookup error: psql: undefined symbol: pqsignal
psql: symbol lookup error: psql: undefined symbol: pqsignal

# ldd /usr/bin/psql |grep pq
     libpq.so.5 => /usr/pgsql-12/lib/libpq.so.5 (0x00007f93fcbe2000)
# /usr/bin/psql --version
psql (PostgreSQL) 9.2.24

How do I resolve this issue, to allow both programs to run on the same 
host?
