It's a shared piece of information that can be used to determine if
the postmaster is up and returning valid results if, at the protocol
level, there was support for having the postmaster return the time at
which it was started. ... like a status bit or query type that
doesn't require authentication that way the startup scripts will
always work regardless of the authentication method in place. -sc
