Re: Urgent!

Lookas as if you've managed to turn off your computer mid-transaction
thereby corrupting the postgreSQL commit logs (pg_clog)...

You should never just turn off a database server... always shut it down
normally... Turning it off was a major mistake. I dont know if you can
recover or not as the system (postgreSQL) now thinks it is in the middle of
a transaction...

As far as recovery goes... You might try a vacuum full and pg_resetxlog
(search the postgreSQL docs for pg_resetxlog)... Other than that you might
need to get Tom Lane's attention on this one...

Hi,

I got this error message when I tried to do pg_dump on the database.

pg_dump: ERROR: invalid memory alloc request size 4294967293
pg_dump: SQL command to dump the contents of table "wordlist" failed:
PQendcopy() failed.
pg_dump: Error message from server: ERROR: invalid memory alloc request
size 4294967293
pg_dump: The command was: COPY public.wordlist (word_id, word, count_word)
TO stdout;

I went to phppgadmin and try to access the worldlist table and it also gives
me following error message:

ERROR: could not access status of transaction 6849340
DETAIL: could not open file "/var/lib/pgsql/data/pg_clog/0006": No such
file or directory

In statement:
SELECT COUNT(*) AS total FROM (SELECT "oid", * FROM "public"."wordlist") AS
sub

CPU was heating up so I turn off the computer and to fix the problem and
after that this occour. I don't know if this has anything to with database
corruption.

This is production server and I don't have latest backup does anyone how to
resolve this.

Please Help
