Bug description: pg_get_result does not block
Description:
------------
According to the pg_connection_busy documentation, if pg_get_result is
called on a pg_send_query that is currently executing, it should block
until results become available.
Occasionally this does not happen if the query had an error in it.
Reproduce code:
---------------
#!/usr/local/bin/php51
<?php
$connStr = sprintf("host=%s dbname=%s user=%s password=%s", 'localhost',
'testdb', 'liam', 'liam');
$dbconn = pg_connect($connStr) or die("Could not connect");
$i = 0;
while (!pg_connection_busy($dbconn)) {
pg_send_query($dbconn, 'i am a syntax error');
pg_get_result($dbconn);
$i++;
}
echo "got a busy signal after $i commands";
?>
Expected result:
----------------
(Loops forever)
Actual result:
--------------
got a busy signal after 221 commands
(actual count varies, but always returns within 1 second. Approximately
1/3 of the time it gives a "happy" run and will loop forever)
Note that if the SQL statement was a valid statement, I cannot get the
erroneous behaviour to occur.
