I was able to easily crash the standby server today just by starting it
and connecting to it via psql. The master was idle. The failure was:
LOG: streaming replication successfully connected to primary
TRAP: FailedAssertion("!(((xmax) >= ((TransactionId) 3)))", File: "procarray.c", Line: 1211)
LOG: server process (PID 12761) was terminated by signal 6: Abort trap
LOG: terminating any other active server processes
My master postgresql.conf was:
wal_level = hot_standby # minimal, archive, or hot_standby
archive_mode = on # allows archiving to be done
archive_command = 'cp -i %p /u/pg/archive/%f < /dev/null ' # command to use to archive a logfile segment
max_wal_senders = 1 # max number of walsender processes
My slave postgresql.conf was:
port = 5433 # (change requires restart)
wal_level = hot_standby # minimal, archive, or hot_standby
archive_mode = off # allows archiving to be done
archive_command = 'cp -i %p /u/pg/archive/%f < /dev/null ' # command to use to archive a logfile segment
hot_standby = on # allows queries during recovery
max_wal_senders = 1 # max number of walsender processes
and my slave recovery.conf was:
restore_command = 'cp /u/pg/archive/%f %p' # e.g. 'cp /mnt/server/archivedir/%f %p'
standby_mode = 'on'
primary_conninfo = 'host=localhost port=5432' # e.g. 'host=localhost port=5432'
Let me know what additional information I can supply.
