Обсуждение: Error while dropping a table
Howdy:
Running PostgreSQL 7.1.3 on RedHat Linux 2.4.7-10.
I'm doing a bit of housecleaning and after dropping a table,
I get this error:
[snip error]
testdb=> drop table db2_se_2002;
NOTICE: RegisterSharedInvalid: SI buffer overflow
DROP
testdb=>
[/snip error]
I've never seen this before. What does it mean?
Should I be concerned?
Thanks!

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. regards, tom lane

--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?

Generally, I would do something like ps -auxww and look for something "idle in transaction" that's been running a long time.
