Re: Postgres Start up Error - Mailing list pgsql-general

Thanks Chetan,
 
The problem is solved by the below command :- :-)

[postgres@ws-test 8.4SS]$  bin/pg_resetxlog -f /hdd-1/PostgresPlus/8.4SS/data

Dear all,

Today I by mistake deleted all the contents of pg_log & pg_xlog directory and my Postgresql refuses to start due to the below error :-

I try to reinstall with the same previous data directory, but it fails again.

Any suggestions to solve it without losing the previous data.


Thanks & best Regards,
