Обсуждение: 8.0B2 checkpoint error on start up

Upgrading 8.0b1 to 8.0b2 in place.
Did I have to do a dump/restore?
Or is this a known problem?

--elein

$ pg_ctl start -D $PGDATA
postmaster starting
/local/pgsql80/data[postgres:cookie]
$ LOG:  database system was shut down at 2004-09-14 13:40:43 PDT
LOG:  invalid magic number D05B in log file 0, segment 34, offset 7495680
LOG:  invalid primary checkpoint record
LOG:  invalid magic number D05B in log file 0, segment 34, offset 7438336
LOG:  invalid secondary checkpoint record
PANIC:  could not locate a valid checkpoint record
LOG:  startup process (PID 4574) was terminated by signal 6
LOG:  aborting startup due to startup process failure

Quick followup...The 8.0 db was only written to by slon
processes.  This problem was replicated by someone else
as well.

The stomp around was to initdb in 8.0b2 and reset up
slony :-(

No, but I think you need a pg_resetxlog.
