Segmentation fault

It used to work before with Alpine 3.18 and LibPQ 1.17.1, but to fix CVEs, we changed the base image to Alpine 3.20 and also updated the LibPQ version. Now it's throwing this error, and I'm not sure what's happening.

Also do note that pg_params contains all the required fields.

Can you try Alpine 3.20 and LibPQ 1.17.1, or are they incompatible?

@iamed2 , I tried it before. It was failing with version 1.17.1 as well, which is why I upgraded to the latest version.
