recommend that people go get Apache's rotatelogs program. Additional benefits are that configuration is done through GUC, rather than externally, and that the postmaster can monitor the log rotator and restart it after failure (though we certainly hope that won't happen often).

# PostgreSQL configuration file
|
|
# -----------------------------
|
|
#
|
|
# This file consists of lines of the form:
|
|
#
|
|
# name = value
|
|
#
|
|
# (The '=' is optional.) White space may be used. Comments are introduced
|
|
# with '#' anywhere on a line. The complete list of option names and
|
|
# allowed values can be found in the PostgreSQL documentation. The
|
|
# commented-out settings shown in this file represent the default values.
|
|
#
|
|
# Any option can also be given as a command line switch to the
|
|
# postmaster, e.g. 'postmaster -c log_connections=on'. Some options
|
|
# can be changed at run-time with the 'SET' SQL command.
|
|
#
|
|
# This file is read on postmaster startup and when the postmaster
|
|
# receives a SIGHUP. If you edit the file on a running system, you have
|
|
# to SIGHUP the postmaster for the changes to take effect, or use
|
|
# "pg_ctl reload".
