You really need to upgrade to 7.2.3/7.2.4. This issue is fixed in 7.2.3.
To fix this problem, stop postmaster, make a dummy clog containing zeros
(/dev/zero), start postmaster. for security you can dump all data then
(perhaps you need to repeat the clog dummy step) and freshly re-insert it.

Subject: [ADMIN] FATAL 2: open of /usr/local/pgsql/data/pg_clog/0943 failed
I have this error in postgres log
FATAL 2: open of /usr/local/pgsql/data/pg_clog/0943 failed: No such file or
directory
When it happend i did indexing on big table (~32M rows)
On small selects, inserts, updates all seems to work fine, but when I try to
do select count(*) from big table or intex it, then server crashes and
automaticaly restarts (file name in error message changes from time to time)
Theare is about 3.5GB free disk space.
Postgres version 7.2.1
Theare is no more unusual messages in log.
What happend?
How to fix this problem?
Google didn't help so much :(
