Re: make pg_ctl more friendly

Hi,

Thank you for working on this! I agree that the current message is not friendly.

v2-0001-PITR-shutdown-should-not-report-error-by-pg_ctl.patch:

- "Examine the log output.\n"),
+ "Examine the log output\n"),
progname);

I don't think that this is needed.

Other than that, the patch looks good and I confirm that after PITR shutdown:

"PITR shutdown"
"update configuration for startup again if needed"

message shows up, instead of:

"pg_ctl: could not start server"
"Examine the log output.".

nitpick: It would be better if the order of the error message cases
and enums is the same ( i.e. 'POSTMASTER_RECOVERY_SHUTDOWN' before
'POSTMASTER_FAILED' in enum )
