Hello.
As there is a known bug, an the 'official bugfix release' is not there yet,
I have a question:

What would commenting out the fatal  line "Async_Unlisten(relname, pid); "
do?

If there is a problem only when the server crashes, I will comment this out,
and go on (noting that I must manually clean up pg_listener on fatal
situations).

I really want to switch to 8.1 (some of my queries, due to the newly
introduced bitmap scan, work like ten times faster). And slony IS the best
choice for 'zero downtime' upgrades :)

Please advise.

Greetings
Marcin Ma?k
