So I've moved it to xlog.c...
I'm pretty sure it shouldn't live in xlog.c, but there may be some
good reason I can't see yet.
Ugh. Yes. transam.c would be rather saner.
Only for the helper to determine if an xid is recent though; txid_ status
stays in adt/xact.c where it belongs along with txid_current() etc.
Fixed, moved to transam.c.
Missed that this causes an undefined reference to GetNextXidAndEpoch()
which is in xlog.c. I knew there was a reason I put it there. So most
recent patch is wrong, use the prior one.
GetNextXidAndEpoch() needs to be in xlog.c because it uses XLogCtl's
shmem copy of checkPoint.nextXidEpoch. So either transam.c needs to
#include xlog.h (which seems a bit backwards) or
TransactionIdInRecentPast() should go in xlog.c.
I don't like either really. Opinion? I'm sure we'll want this
functionality in other places as part of dealing with the problems
discussed upthread with 'xid' exposed to users.
You could put it to txid.c where all the other txid stuff is in?
