# # # Sets how many cleanup cycles to run before a vacuum is done. # Range: [0,100], default: 3 #vac_frequency=3 # Aging interval to use for deleting old events and for trimming # data from sl_log_1/sl_log_2 #cleanup_interval="10 minutes" # Debug log level (higher value ==> more output).

If the sync is picked # up by the subscriber, processed and finished before the transaction # commits, this transaction's changes will not be replicated until the # next SYNC. But if all application activity suddenly stops, # there will be no more sequence bumps, so the high frequent -s check # won't detect that.
