There really isn't any difference between ERROR and PANIC in this
context: any error is going to result in startup failure (cf. elog.c's
behavior when there is no exception catcher). I think that the older rmgr
code may have been written using PANIC to make it more obvious that that
would happen, but it doesn't matter. Not sure if there's much point in
trying to standardize.
The stuff that is LOG should perhaps be reduced to DEBUG1 --- I doubt
that it has any non-debugging purpose.
