recoveryStopReason is always acquired but it is used only after

call getRecoveryStopReason() directly at the required place?
Robert commented on the same thing, see my reply there.
0002:
heapam.c, clog.c, twophase.c, dbcommands.c doesn't need xlogrecvoer.h.
Cleaned that up in v7, thanks!
XLogRecCtl
"Rec" looks like Record. Couldn't we use "Rcv", "Recov" or just
"Recovery" instead?
I never made that association before, but now I cannot unsee it :-). I
changed it to XLogRecoveryCtl.
TimeLineID PrevTimeLineID;
TransactionId oldestActiveXID;
bool promoted = false;
EndOfWalRecoveryInfo *endofwal;
bool haveTblspcMap;
This is just a matter of taste but the "endofwal" looks somewhat
alien in the variables.
Changed to "endOfRecoveryInfo".
xlog.c:
+void
+SwitchIntoArchiveRecovery(XLogRecPtr EndRecPtr)
Isn't this a function of xlogrecovery.c? Or rather isn't
minRecoveryPoint-related stuff of xlogrecovery.c?
Updating the control file is xlog.c's responsibility. There are two
different minRecoveryPoints:
1. xlogrecovery.c has a copy of the minRecoveryPoint from the control
file, so that it knows when we have reached consistency.
2. xlog.c is responsible for updating the minRecoveryPoint in the
control file, after consistency has been reached.
SwitchIntoArchiveRecovery() is called on the transition.
