Error while dropping a table

NOTICE: RegisterSharedInvalid: SI buffer overflow

I've never seen this before. What does it mean?

It's just an internal debugging message. (It should have been
downgraded to DEBUG level awhile ago, and was in 7.2.)

Should I be concerned?

This suggests that you've got some other backend that's been sitting
in an open transaction for a long time. While that isn't directly
harmful, it'll probably be blocking VACUUM, so you might want to
figure out which client is holding the open transaction and zap it.

Thanks for the reply:

--Okay, but now, how do I find out what client is holding
--the table hostage? Generally, I would do something like
--'pg_query' and see what people are doing and against
--whatever table ... but it doesn't appear to be the case
--in this matter.

--Any particular method in finding this out?

ps -auxww and look for something "idle in transaction" that's been
running a long time.
