# PostgreSQL configuration file |

# ----------------------------- |

# |
||||||
|
# This file consists of lines of the form |
||||||
|
# |
||||||
|
# name = value |
||||||
|
# |
||||||
|
# (The `=' is optional.) White space is collapsed, comments are |
||||||
|
# introduced by `#' anywhere on a line. The complete list of option |
||||||
|
# names and allowed values can be found in the PostgreSQL |
||||||
|
# documentation. Examples are: |
||||||
|
|
||||||
|
#log_connections = on |
||||||
|
#fsync = off |
||||||
|
#max_backends = 64 |
||||||
|
|
||||||
|
# Any option can also be given as a command line switch to the |
||||||
|
# postmaster, e.g., `postmaster --log-connections=on'. Some options |
||||||
|
# can be set at run-time with the `SET' SQL command. |
