---|
| 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. |
