problems after pg_resetxlog
Hi, i had a server crash and after that , postgres refused to start, i
read on the list that pg_resetxlog could help me, indeed, after i run
pg_resetxlog dir_data, postgres started again, but i look a lot of these

Increasing the WAL start address might help (see the pg_resetxlog man
page). Realize that you're probably going to be dealing with corrupted
data, however :-(

Yeah, i know, but i only want to be able to finish the dump, i must
execute the
pg_resetxlog again with the -l flag?

drwx------ 2 postgres postgres 4096 Apr 22 2005 archive_status
So :
pg_resetxlog -l 0x01, 0x98, 0x25 dir_data
Is this ok?
