-        Specify the compression level to use in archive formats that
-        support compression.  (Currently only the custom archive
-        format supports compression.)
+        Specify the compression level to use.  Zero means no compression.
+        For the custom archive format, this specifies compression of
+        individual table-data segments, and the default is to compress
+        at a moderate level.
+        For plain text output, setting a nonzero compression level causes
+        the entire output file to be compressed, as though it had been
+        fed through gzip; but the default is not to compress.
+        The tar archive format currently does not support compression at all.
