  5. <code class="command">COMMIT</code> commits the current transaction. All
  6. changes made by the transaction become visible to others
  7. and are guaranteed to be durable if a crash occurs.

  11. If <code class="literal">AND CHAIN</code> is specified, a new transaction is
  12. immediately started with the same transaction characteristics (see <a class="xref" href="sql-set-transaction.html" title="SET TRANSACTION"><span class="refentrytitle">SET TRANSACTION</span></a>) as the just finished one. Otherwise,
  13. no new transaction is started.

  15. Use <a class="xref" href="sql-rollback.html" title="ROLLBACK"><span class="refentrytitle">ROLLBACK</span></a> to
  16. abort a transaction.
  17. </p><p>
  18. Issuing <code class="command">COMMIT</code> when not inside a transaction does
  19. no harm, but it will provoke a warning message. <code class="command">COMMIT AND
  20. CHAIN</code> when not inside a transaction is an error.

  26. The command <code class="command">COMMIT</code> conforms to the SQL standard. The
  27. form <code class="literal">COMMIT TRANSACTION</code> is a PostgreSQL extension.
