The attached patch implements START TRANSACTION, per SQL99. The

Browse Source 
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.

[ Regression tests removed, per Peter.]
