I've noticed, that cfbot complains about this patch [1], since:

Duplicate OIDs detected:
3423
found 1 duplicate OID(s) in catalog data

At the same time it's quite minor problem, so I'm moving it to the nexc CF as
"Needs review".

Also since it's performance related patch, and the latest tests I see in the
history of this topic were posted around the time of the initial thread (which
was quite some time ago), could we expect to see some new benchmarks with this
patch and without? Probably the positive difference would be obvious, but
still.
