# pg_options controls certain options and tracing features of the
|
|
# PostgreSQL backend. It is read by postmaster and postgres before
|
|
# command line arguments are examined, so command line arguments
|
|
# will override any settings here.
|
|
|
|
# This file should be located at $PGDATA/pg_options. In Debian, this is
|
|
# a symbolic link to /etc/postgresql/pg_options.
|
|
|
|
# The capitalised words refer to the internal #defines in the source code
|
|
# which use these options. Options can be turned on and off while the
|
|
# postmaster is running by editing this file and sending a SIGHUP to
|
|
# the postmaster.
