Ian Barwick 97d83bd443 standby switchover: add hint for diagnosing remote DB connection failure ...

Output a command, which when excuted on the local node (promotion
candidate) will attempt to remotely connect to the demotion candidate
and display both the connection message encountered and the connection
parameters used.

This is useful for corner-cases where the connection normally succeeds if a
particular environment variable (e.g. PGPORT) is normally set, but is
not set in the environment where SSH is executed.
