pg_dump warning message

Subject: pg_dump warning message

Postgres version: 7.3.4
Environment: Solaris (SunOS 5.9) Ultra-250
We use pg_dump to do a nightly export of all databases, via these commands:

for instance in $(get_instances) ; do
   su - ${pg_user} -c "${pg_home}/bin/pg_dump -c -C -D -F c -f ${outfile} 
   gzip ${outfile}

The pg_dump switches indicate a "custom" file format, and the output file 
is a standard plain-text UNIX file.
Nevertheless, when the export runs, it throws this warning for each 
database instance:

pg_dump: [archiver] WARNING: requested compression not available in this 
installation - archive will be uncompressed

This does not appear to affect the contents of the export file--but it 
would be nice to understand what is generating these messages--and to 
eliminate the chatter (which the system crontab treats as error messages);
