pg_get_result() hangs for query length > 65535

[John Ramsden]

I have a script running on PHP v4.3.6 (cgi) that hangs forever
in a call to the Postgres pg_get_result() function when and only
when the query length is 65536 or more bytes.

The query is a simple INSERT, of a single ASCII value into a
'text' type field, and works fine for shorter queries.

(As the code first calls pg_escape_strin g() on the value to be
inserted, I'm sure the problem doesn't relate to bad characters
in the data.)

Anyone have any ideas? My impression is that few PHP coders use
pg_send_query() and pg_get_result() , despite this being the only
way (AFAIK) of getting specific error codes/text when something
goes wrong (in which event pg_query() just returns false).

The following is an extract from the offending code:

if ($db_type == 'mysql')
{
$qry_id = @mysql_query ($x_qry, $x_db_conn);

$g_db_err_no = mysql_errno ();
$g_db_err_str = mysql_error ();
}

else if ($db_type == 'postgres')
{
# Because pg_query() returns FALSE if the query fails, one must must
# use pg_send_query() and pg_get_result() to get the result handle.
#
# $qry_id = @pg_query ($x_db_conn, $x_qry);
#
if (! pg_send_query ($x_db_conn, $x_qry))
{
die ("pg_send_query ");
}
!!!!!!!! QUERY OF LENGTH 64K OR MORE HANGS IN FOLLOWING pg_get_result() CALL
if (! ($qry_id = pg_get_result ($x_db_conn)))
{
die ("pg_get_result ");
}

# jr.debug
error_log (" past pg_get_result() !\n", 3, '/tmp/hack.log');

# pg_result_error (), available from PHP v4.2.0+, like pg_result_statu s(),
# returns a better result then pg_last_error() , as the latter may be set
# by all kinds of internal calls and thus not reflect the app-level error.
#
$g_db_err_no = pg_result_statu s ($qry_id);
$g_db_err_str = pg_result_error ($qry_id);
}

else if ($db_type == 'mssql')
{
