Обсуждение: START TRANSACTION

The attached patch implements START TRANSACTION, per SQL99. The
functionality of the command is basically identical to that of
BEGIN; it just accepts a few extra options (only one of which
PostgreSQL currently implements), and is standards-compliant.
The patch includes a simple regression test and documentation.

Cheers,

Neil

Oh, forgot to mention two things: I also removed the grammar's
"support" for chained transactions, since it was basically non-
existent (I don't see the advantage of producing an "chained
transactions not support" error rather than a generic one).
I also renamed the 'opt_level' production to 'iso_level', since
it's not "optional".

Cheers,

Neil

Very nice patch, but I don't think we need the regression test.  It's a
bit too simple.
