Thanks to all of you who responded so quickly. I can confirm collectively that
postmaster is
working again and my db is no worse for the wear (as far as I can tell). Those
of you who
mentioned that I needed to run postmaster in the background were correct. I'm
not sure
what the deal was with the mysterious process. I was a bit startled when I
deleted it and it
spit that string of alerts at me, but everything is back up and I am quite
relieved.
