Neil Conway and I opened this VERY BIG can of worms a couple of years
ago on hackers.
I can't find the references to it in the archives. I think I need to go
back more than the start of 2005. And I can't remember how to do that.
It was in relation to CLUSTER on a table and how previous transactions
would not use the correct view of the table.
I recall something to do with issues relating to reading the catalog
before transaction startup and problems with needing a transaction to
use the catalog.
My memory of it is fuzzy. If Neil or Tom remember the discussion they
may be able to post a link.
Sorry if this wasn't much help.
