<function>pg_fetch_assoc</function> returns an associative array that
corresponds to the fetched row (tuples/records). It returns
&false;, if there are no more rows.
</para>
<para>
<function>pg_fetch_assoc</function> is an extended version of
<function>pg_fetch_row</function>. In addition to storing the
data in the numeric indices (field index) to the result array, it
also stores the data in associative indices (field name) by
default.
</para>
<para>
<parameter>row</parameter> is row (record) number to be
retrieved. First row is 0.
</para>
<para>
<function>pg_fetch_assoc</function> is NOT significantly
slower than using <function>pg_fetch_row</function>, while it
provides a significant ease of use.

<para>
<function>pg_unescape_bytea</function> unescapes string from
bytea datatype. It returns unescaped string (binary).
</para>
<note>
<para>
When you SELECT bytea type, PostgreSQL returns octal byte value
prefixed by \ (e.g. \032). Users are supposed to convert back to
binary format by yourself.
</para>
<para>
This function requires PostgreSQL 7.2 or later. With PostgreSQL
7.2.0 and 7.2.1, bytea type must be casted when you enable
multi-byte support. i.e. <literal>INSERT INTO test_table (image)
VALUES ('$image_escaped'::bytea);</literal> PostgreSQL 7.2.2 or
later does not need cast. Exception is when client and backend
character encoding does not match, there may be multi-byte
stream error. User must cast to bytea to avoid this error.
