Hi,
You are right. I've already seen sequences increase up to 24 or 32 after
a failover with PITR.
However, I'm also using PITR in order to do switchover. In this case, I
think that nothing
should change...
But, I recognize that using PITR for switchover is rather an
"unsupported" functionnality...
Thank you,
