Applied after rather a lot of hacking.
Aside from the issues previously raised, I changed the NOTIFY syntax to
include a comma between channel name and payload. The submitted syntax
with no comma looked odd to me, and it would have been a real nightmare
to extend if we ever decide we want to support expressions in NOTIFY.
I found a number of implementation problems having to do with wraparound
behavior and error recovery. I think they're all fixed, but any
remaining bugs are probably my fault not yours.
regards, tom lane
