.SH DESCRIPTION
 | 
						|
This command begins a user transaction which Postgres will guarantee is
 | 
						|
serializable with respect to all concurrently executing transactions.
 | 
						|
Postgres uses two-phase locking to perform this task.  If the transaction
 | 
						|
is committed, Postgres will ensure that all updates are done or none of
 | 
						|
them are done.  Transactions have the standard ACID (atomic,
 | 
						|
consistent, isolatable, and durable) property.
 |
