What version of PostgreSQL is your server running and what client
software are you using?  PostgreSQL 7.3 had a server-side autocommit
setting, but it caused problems with some clients so 7.4 got rid
of it and left autocommit up to the client.  How to enable or disable
client-side autocommit depends on the client software, but if you're
able to execute a BEGIN (or START TRANSACTION) statement then you
should be inside a transaction until you execute COMMIT (or END)
or ROLLBACK.  That is, unless your client intercepts these statements
and does whatever it wants....
