[Issue 2665] Add temp logging to help troubleshoot db connection fail…

…ures (#2816)

## Summary
Partially Fixes #2665

### Time to review: __1 min__

## Changes proposed
> What was added, updated, or removed in this PR.

Added `sslmode` to Postgres connection string. Also added some temporary
logging to help troubleshoot db connection failures from analytics code.
I will remove the logging in a future PR, as soon as I find the cause of
the db connection failures.

## Context for reviewers
> Testing instructions, background context, more in-depth details of the
implementation, and anything else you'd like to call out or ask
reviewers. Explain how the changes were verified.

Analytics step functions have been deployed but when they execute their
attempted connections to Postgres always fail.

## Additional information
> Screenshots, GIF demos, code examples or output to help show the
changes working as expected.
