The documentation states about the logging collector:
"Note: It is possible to log to stderr without using the logging collector; the log messages will just go to wherever
theserver's stderr is directed. However, that method is only suitable for low log volumes, since it provides no
convenientway to rotate log files. Also, on some platforms not using the logging collector can result in lost or
garbledlog output, because multiple processes writing concurrently to the same log file can overwrite each other's
output."
(From here: http://www.postgresql.org/docs/9.1/interactive/runtime-config-logging.html)
By "multiple processes", does this refer to multiple postgresql servers running on the same machine? If we only have 1
postgresqlserver running on the machine, is it safe to leave logging_collector off and log to stderr?
