Hi I seem to have an 8.3.9 database with a broken xlog,

PANIC: heap_insert_redo: invalid max offset number

My plan is to run pg_resetxlog.
Hopefully it then starts up.
Test recent data as thoroughly as possible - (script some Select * ' s?)
If ok -> curse ops and their raid caches
If not -> curse ops and tell them to recover from backup (v. large and
therefore very slow process).

Can anyone give me feedback on this plan?

Cheers
Colin.
