When logging to <application>syslog</> is enabled, this parameter
4345+
determines how messages are delivered to syslog. When on (the
4346+
default), messages are split by lines, and long lines are split so
4347+
that they will fit into 1024 bytes, which is a typical size limit for
4348+
traditional syslog implementations. When off, PostgreSQL server log
4349+
messages are delivered to the syslog service as is, and it is up to
4350+
the syslog service to cope with the potentially bulky messages.

<para>
4354+
If syslog is ultimately logging to a text file, then the effect will
4355+
be the same either way, and it is best to leave the setting on, since
4356+
most syslog implementations either cannot handle large messages or
4357+
would need to be specially configured to handle them. But if syslog
4358+
is ultimately writing into some other medium, it might be necessary or
4359+
more useful to keep messages logically together.
