SQL statements: begin and end

I see everybody using the following PostgreSQL statements:

"begin" instead of "begin work"
"end" instead of "commit work"

This is really bad, because it is not standard, and can easily be taken for
a statement block, which it is definitely not ! It is a transaction block.

I vote for issuing a NOTICE for these in V7 and remove them in V8,
at least the single "end"

Bruce, please don't use "begin" and "end" in your book.
