Joao,
If you had send the Email to pgsql-admin mailing list you would have got a
faster answer to ur query..
here is what i managed to do:-
1. I deleted the
$ls -lart the pg_clog folder
total 756
-rw------- 1 postgres users 262144 2006-04-10 17:16 0001
-rw------- 1 postgres users 262144 2006-04-10 17:16 0000
drwx------ 2 postgres users 4096 2006-04-10 17:16 .
-rw------- 1 postgres users 229376 2006-05-31 18:17 0002
drwx------ 10 postgres users 4096 2006-06-02 12:22 ..
$ mv 0002 ../
$ ls
0000 0001
$psql regression
regression=# select count(1) from accounts;
ERROR: could not access status of transaction 2225656
DETAIL: could not open file "pg_clog/0002": No such file or directory
regression=# \q
This Error came since the 0002 file from the pg_clog folder was missing.
Since the logs are missing from pg_clog folder can perfom pg_resetxlogs to
reset the logs and bring up the database.
$ /usr/local/pgsql/bin/pg_ctl -D /newdisk/postgres/data -l
/newdisk/postgres/data_log stop
waiting for postmaster to shut down... done
postmaster stopped
$ /usr/local/pgsql/bin/pg_resetxlog -x 2999800 /newdisk/postgres/data
Transaction log reset
The Value 2999800 u can get if u see the postgresql output file during
startup or using
grep "next transaction ID" /newdisk/postgres/data_log
than did the following:-
/usr/local/pgsql/bin/psql regression
regression=# select count(1) from accounts;
count
---------
1000001
(1 row)
regression=# \q
You can get more info from
http://unix.business.utah.edu/doc/ap.../postgres/post gres-html/app-pgresetxlog.html
Hope this gives u some usefull information in solving ur recovery condition.
