# |
| 7 |
|
|
# name = value |
| 8 |
|
|
# |
| 9 |
|
|
# (The '=' is optional.) White space may be used. Comments are introduced |
| 10 |
|
|
# with '#' anywhere on a line. The complete list of option names and |
| 11 |
|
|
# allowed values can be found in the PostgreSQL documentation. The |
| 12 |
|
|
# commented-out settings shown in this file represent the default values. |
| 13 |
|
|
# |
| 14 |
|
|
# Please note that re-commenting a setting is NOT sufficient to revert it |
| 15 |
|
|
# to the default value, unless you restart the postmaster. |
| 16 |
|
|
# |
| 17 |
|
|
# Any option can also be given as a command line switch to the |
| 18 |
|
|
# postmaster, e.g. 'postmaster -c log_connections=on'. Some options |
| 19 |
|
|
# can be changed at run-time with the 'SET' SQL command. |
| 20 |
|
|
# |
| 21 |
|
|
# This file is read on postmaster startup and when the postmaster |
| 22 |
|
|
# receives a SIGHUP. If you edit the file on a running system, you have |
| 23 |
|
|
# to SIGHUP the postmaster for the changes to take effect, or use |
| 24 |
|
|
# "pg_ctl reload". Some settings, such as listen_address, require |
| 25 |
|
|
# a postmaster shutdown and restart to take effect. |
