It's because we are very old and we had custom software originally, way back in the 70 and 80's when we were first getting computers. When OpenVMS(the system our custom software was running on) was EOL'd, the existing team was given a lot of leeway to find a replacement. We were not very excited about the options and we had programmer staff already dedicated to the old custom software. Also users wanted "GUI" and "Web". So we implemented a new system in Python and PostgreSQL. PG functions are written in Python too.

I wasn't part of the original team, but I was there for the re-write. I brought in Python and PostgreSQL and I created two-way sync between the old OpenVMS system and PostgreSQL, so we could take our time and didn't need to have a big cutover date. That was a HUGE selling point that got everyone on board.
