I used to think ctid is the same as rowid in Oracle,
where rowid access is the fastest. Is it wrong?
After all, why oid is faster then ctid?
I consider using index of course. I just cannot
believe it is the best what I can do here.

I played with fresh database.
server version is 8.0.3, enable_tidscan is on,
looks like hints have no effect.
Thanks.
