postgresql error PANIC: could not locate a valid checkpoint record -

when load postgres server (v9.0.1) panic prevents starting:

panic: not locate valid checkpoint record

how can prepare this?

it's looking checkpoint record in transaction log doesn't exist or corrupted. can determine if case running:

class="lang-sh prettyprint-override">pg_resetxlog datadir

if transaction log corrupt, you'll see message like:

the database server not shut downwards cleanly. resetting transaction log might cause info lost. if want proceed anyway, utilize -f forcefulness reset.

you can follow instructions , run -f forcefulness update:

class="lang-sh prettyprint-override">pg_resetxlog -f datadir

that should reset transaction log, leave database in indeterminate state explained in postgresql documentation on pg_resetxlog:

if pg_resetxlog complains cannot determine valid info pg_control, can forcefulness proceed anyway specifying -f (force) switch. in case plausible values substituted missing data. of fields can expected match, manual assistance might needed next oid, next transaction id , epoch, next multitransaction id , offset, , wal starting address fields. these fields can set using switches discussed below. if not able determine right values these fields, -f can still used, recovered database must treated more suspicion usual: immediate dump , reload imperative. not execute data-modifying operations in database before dump, such action create corruption worse.
