Please note that PM_STARTUP mode is very very short-lived. It only
starts happening when postmaster launches the startup process, and
before the startup process begins WAL replay (as changed by
sigusr1_handler in postmaster.c). Once WAL replay begins, the PM status
changes to PM_RECOVERY. So I don't think we really care all that much
what message is logged in this case. It changes very quickly into the
CAC_NOTCONSISTENT message anyway. For this state, it seems okay with
either what James submitted in v7, or what Fujii said.
However, for this one
+ case CAC_NOTCONSISTENT:
+ if (EnableHotStandby)
+ ereport(FATAL,
+ (errcode(ERRCODE_CANNOT_CONNECT_NOW),
+ errmsg("the database system is not accepting connections"),
+ errdetail("Consistent recovery state has not been yet reached.")));
Maybe it makes sense to say "... is not accepting connections *yet*".
That'd be a tad redundant with what the DETAIL says, but that seems
acceptable.
