How close to this is PG's COPY? I get surprisingly good results using COPY
with jdbc on smallish systems (now if that patch would make into the mainstream
PG jdbc support!) I think COPY has a bit more overhead than what a Bulkload
feature may have, but I suspect it's not that much more.

|| Steve, I do not know. But am reading the docs now, and should figure it
out. Ask
me later if you remember. Oracle's "direct path" is a way of just slamming
blocks
filled with rows into the table, above the high water mark. It sidesteps
freelist
management and all manner of intrablock issues. There is a "payback", but
the benefits
far far outweigh the costs.

It may not be that far off if you can use COPY instead of INSERT. But comparing
Bulkload to INSERT is a bit apples<->orangish.
|| Oh! I see! I had no idea I was doing that! Thanks for pointing it out
clearly to me. Yea, I would
say a full transactional INSERT of 5K rows/sec into an indexed-table is a
near-mythology without significant
caveats (parallelized, deferred buffering, etc.)
