Commit Message

conncheck: preserve and report idle server errors (#1843)

Use `MSG_PEEK` for the idle connection check so it does not consume the
first byte. When data is pending, try reading the server's ERR packet
through the existing TLS and compression layers before discarding the
connection. Log the original error number, SQLSTATE, and message instead
of only `unexpected read from socket`.

Fixes #1392.
