OK. I plan to gather the usual suspects and try to get an accurate
picture of the chain of events first thing tomorrow. Then we'll likely
proceed as you suggest.
Thinking about your comments and reading xlog.c, it almost seems as
though the mount points were momentarily reversed between /replica and
/production. I.e. that the /production mount point was used near the
beginning of StartupXLOG() for ReadControlFile(), and the /replica mount
point was used at the end of StartupXLOG() for UpdateControlFile(). But
I have no idea how that could happen.
Thanks,
Joe
