The following bug has been logged on the website:

Bug reference: 6518
Logged by: Janning Vygen
Email address: vygen(at)kicktipp(dot)de
PostgreSQL version: 9.1.2
Operating system: Linux / Debian
Description:

I am using postgresql 9.1.2 from debian backports.

The documentation for 9.1 says about archive_command:

"Any messages written to stderr from the script will appear in the database
server log, allowing complex configurations to be diagnosed easily if they
fail."

<http://www.postgresql.org/docs/9.1/static/continuous-archiving.html#BACKUP-TIPS>

This is not true if log_destination=syslog

Messages to sdterr does not appear at all anywhere. I prefer syslog because
of pgfouine.

Great if it can be fixed. At least this should be documented.

kind regards
Janning
