Fix transient errors in CI due to DB connection issues

[Blckbrry-Pi]

node-postgres is repeatedly throwing this error in CI

error: Uncaught (in promise) ConnectionError: The session was terminated unexpectedly
      throw new ConnectionError("The session was terminated unexpectedly");

What I know so far:

• It's erroring here: https://deno.land/x/[email protected]/connection/connection.ts?source=#L166
• Postgres is sending a null byte (or not sending a byte at all?)
• Postgres logs might be helpful for debugging this
• The issue is in sending the startup message
