Bug description:Emulate prepares behave strangely with PARAM_BOOL
Description:
------------
On postgresql when I use ATTR_EMULATE_PREPARES binding params or values
with PARAM_BOOL behave strangely.
Disabling ATTR_EMULATE_PREPARES resolve the problem.
(driver specific PGSQL_ATTR_DISABLE_NATIVE_PREPARED_STATEMENT generates
same problem)
(Related to bug #38386 ?)
Test script:
---------------
$db = new PDO('pgsql:dbname=testdb;user=postgres');
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, true);
//$db->setAttribute(PDO::PGSQL_ATTR_DISABLE_NATIVE_PREPARED_STATEMENT,
true);
//CREATE TABLE t(a boolean, b boolean)
$stmt = $db->prepare("INSERT INTO t(a,b) VALUES (true,false)");
$stmt->execute();
print_r($stmt->errorInfo());
$stmt = $db->prepare("INSERT INTO t(a,b) VALUES (:test,:test)");
$stmt->bindValue('test', false, PDO::PARAM_BOOL);
$stmt->execute();
print_r($stmt->errorInfo());
$stmt = $db->prepare("SELECT * FROM t WHERE :test");
$stmt->bindValue('test', true, PDO::PARAM_BOOL);
$stmt->execute();
print_r($stmt->errorInfo());
print_r($stmt->fetchAll());
Expected result:
----------------
Works without errors.
Actual result:
--------------
