Hi, For special testing reason, I am trying to restore PG from a backup that the basebase is from Standby and WAL files are from Master. During recovery phase, for every WAL file process, it returned 'invalid resource manager ID in primary checkpoint record' and paused, I had to manually run "$PGBIN/pg_resetxlog -f $PG_DATA" many times, is there a way to set PG to ignore this kind of errors. LOG: database system was shut down at 2013-09-10 03:06:29 : starting archive recovery LOG: restored log file "00000001000000B9000000CA" from archive LOG: invalid resource manager ID in primary checkpoint record LOG: invalid secondary checkpoint link in control file PANIC: could not locate a valid checkpoint record LOG: startup process (PID 17969) was terminated by signal 6: Aborted LOG: aborting startup due to startup process failure .
