bump lib/pq ftom 1.2 to 1.10

    I'm seeing "broken pipe" errors when working with CRDB using sqlx.
    The issue seemed to be the tcp connections were diconnected while the conns
    in db driver (pq) still has stale connection.

    It happens more often when the DB is behind a proxy.
    In our cases, the pods were proxied by the envoy sidecar.

    There were other instances on the community reporting similar issues,
    and took different workaround by sebding perodic dummy queries in app
    mimicing keepalive, enlenghthen proxy idle timeout, or shortening the
    lifetime of db conn.

    This has been reported and fixed by the lib/pq upstream in v1.9+

      lib/pq#1013

      lib/pq#723
      lib/pq#897
      lib/pq#870
