PGAdapter throwing a lot of PGExceptions and SocketExceptions

[hiradp]

Sorry in advance for subpar issue creation, but I don't have much to go off.

We're seeing a ton of errors like this:

Our set up is:

• Rust application using https://github.com/launchbadge/sqlx in main container
• PGAdapter as a sidecar
• Running in a cloud run service.

It's hard for me to debug to figure out where the issue is. Any pointers would be much appreciated 🙇
