Re: failed archive command

I tried to use only %p to specify the path, but it does not seem to output the full path according to the server log. It only starts at /pg_xlog:

archive_command = '/usr/bin/scp -B "%p" postgres(at)172(dot)20(dot)204(dot)55:/Volumes/DataDrive/wals_from_master/%f'

DETAIL: The failed archive command was: /usr/bin/scp -B "pg_xlog/000000010000007400000086" postgres(at)172(dot)20(dot)204(dot)55:/Volumes/DataDrive/wals_from_master/000000010000007400000086

Also, if I specify the full path (like I was doing before) and execute the scp command as the postgres user on the master, it works (see output below). So I don't understand why it's not working when the postgres server tries to execute the same command.
