+ log_line_info (string)
+
+
+ This is a printf type string that is output before the
+ beginning of each log line. The default is an empty string.
+ Any recognised escape is replaced as set
+ out below - anything else that looks like an escape is ignored. Other
+ characters are copied straight to the log line. Some escapes are
+ only recognised by session processes, and do not apply to other
+ processes not controlling sessions. Syslog produces its own
+ timestamp and process ID information, so you probably do not want to
+ use those escapes if you are using Syslog.
+
+
+
+
+ Escape
+ Effect
+ Session only
+
+
+
+
+ %t
+ Timestamp
+ No
+
+
+ %p
+ Process ID
+ No
+
+
+ %%
+ literal %
+ No
+
+
+ %l
+ Number of the log line for each process,
+ starting at 1
+ No
+
+
+ %x
+ Does not produce any output, but tells non-session
+ processes to stop at this point in the string. Ignored by
+ session backends.
+ No
+
+
+ %u
+ User Name
+ Yes
+
+
+ %d
+ Database Name
+ Yes
+
+
+ %s
+ Session Start Timestamp
+ Yes
+
+
+ %c
+ Session Cookie. A unique identifier for each session.
+ It is just 2 hexadecimal numbers separated by a dot. The numbers
+ are the Session Start Time and the Process ID, so this can also
+ be used as a space saving way of printing these items.
+ Yes
+
+
+ %i
+ Command Tag. This is the context in which the log
+ line was generated.
+ Yes
+
+
+ %r
+ Remote Hostname or IP address, and Remote Port
+ Yes
