dd_opfamily_version_check.diff (application/octet-stream) patch

Someone (me) didn't get the version check for part of psql's \dd
command quite right. I was using a 9.2 client on a 9.1 server and got
this when I ran \dd:

ERROR:  function pg_catalog.pg_opfamily_is_visible(oid) does not exist
LINE 33:   AND pg_catalog.pg_opfamily_is_visible(opf.oid)

since pg_opfamily_is_visible() is only available for 9.2 and up.
Attached is a simple fix.
