the long-term plan for this behavior for quite some time, but it is only possible now that DELETE has a USING clause so that the user can join other tables in a DELETE statement without relying on this behavior.

# 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.
|
|
#
|
|
# Please note that re-commenting a setting is NOT sufficient to revert it
|
|
# to the default value, unless you restart the postmaster.
|
|
#
|
|
# 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". Some settings, such as listen_address, require
|
|
# a postmaster shutdown and restart to take effect.
