    <para>
     <function>pg_fetch_result</function> returns values from a
     <parameter>result</parameter> resource returned by
     <function>pg_query</function>. <parameter>row</parameter>
     is integer.  <parameter>field</parameter> is field name (string)
     or field index (integer). The <parameter>row</parameter>
     and <parameter>field</parameter> specify what cell in the table
     of results to return.  Row numbering starts from 0.  Instead of
     naming the field, you may use the field index as an unquoted
     number.  Field indices start from 0.

    <para>
     PostgreSQL has many built in types and only the basic ones are
     directly supported here.  All forms of <type>integer</type> <!--
     FIXME: is that still true? PHP supports boolean&null now... -->
     <!-- Yes, supporting boolean&null breaks
     scripts. pg_fetch_array() can be used instead. I might take of
     this issue with additional ini directive. yohgaki@php.net -->
     types are returned as <type>integer</type> values.  All forms of
     float, and real types are returned as <type>float</type> values.
     Boolean is returned as &quot;t&quot; or &quot;f&quot;.  All
     other types, including arrays are returned as strings formatted
     in the same default PostgreSQL manner that you would see in the
     <command>psql</command> program.
