Closes https://github.com/neondatabase/neon/issues/3114
Adds more typization into errors that appear during protocol messages (`FeMessage`), postgres and walreceiver connections.
Socket IO errors are now better detected and logged with lesser (INFO, DEBUG) error level, without traces that they were logged before, when they were wrapped in anyhow context.
This fixes all kinds of problems related to missing params,
like broken timestamps (due to `integer_datetimes`).
This solution is not ideal, but it will help. Meanwhile,
I'm going to dedicate some time to improving connection machinery.
Note that this **does not** fix problems with passing certain parameters
in a reverse direction, i.e. **from client to compute**. This is a
separate matter and will be dealt with in an upcoming PR.
