I don't understand why this patch record has been kept aliv for so long,
since no new version has been sent in ages. If this patch is really
waiting on the author, let's see the author do something. If no voice
is heard very soon, I'll close this patch as RwF.
If others want to see this feature in PostgreSQL, they are welcome to
contribute.
