Re: [HACKERS] FOR SHARE LOCK clause ?]

OK, I have retrieved Vadim's original proposal for LLL from July. (No
wonder I didn't remember it.)

He basically describes the MVCC system at the bottom, and at the top, I
am discussing a way to avoid a mapping of SCN's to XID's. There are
other postings that finally resolved the issue. At least Vadim didn't
say I was way off, so somehow he resolved it.

This is an great benefit. We don't have to apologize about table-level
locking anymore. I didn't think it could be done, and Vadim's changes
kind of came as a surprise to me, probably because I didn't understand
the ramifications when discussing it in July.
