>From man begin:
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.
