<chapter id="libpq">

maintain the <structname>PGresult</structname> abstraction. Use the accessor functions below to get

at the contents of <structname>PGresult</structname>. Avoid directly referencing the fields of the

<structname>PGresult</structname> structure because they are subject to change in the future.

(Beginning in <productname>PostgreSQL</productname> 6.4, the

definition of <type>struct</> behind <structname>PGresult</> is not even provided in <filename>libpq-fe.h</>. If you

have old code that accesses <structname>PGresult</structname> fields directly, you can keep using it

by including <filename>libpq-int.h</filename> too, but you are encouraged to fix the code

soon.)

If <quote>autocommit</quote> is on, multiple queries sent in a single

function call are processed in a single transaction.
