Event trigger code comment duplication

Skimming through the code in event_trigger.c and noticed that while most of
the stanzas that reference IsUnderPostmaster refer back to the code comment
beginning on line 675 the block for table rewrite copied it in
verbatim starting at line 842.  The currentEventTriggerState comment at
lines 730 and 861 seem to be the same too.

I did also notice a difference with the test on line 861 compared to line
785 though I unable to evaluate whether the absence of a "rewriteList" is
expected (there is a "dropList" at 785 ...).
