I have confirmed this. The issue with disabling emulation prepares for this
purpose is that it sends the query through PQprepare, then PQexec. If you're
using middleware such as pgbouncer, this won't work.

Yes! _Yesterday_ I have * with the same bug. Solution: install 5.3.13 or
disable emulate prepares (but it is sometimes necessary).

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:
--------------
Array
(
[0] => 00000
[1] =>
[2] =>
)
Array
(
[0] => 42804
[1] => 7
[2] => ERROR: column "a" is of type boolean but expression is of type
integer
LINE 1: INSERT INTO t(a,b) VALUES (0,'0')
^
HINT: You will need to rewrite or cast the expression.
)
Array
(
[0] => 42804
[1] => 7
[2] => ERROR: argument of WHERE must be type boolean, not type integer
LINE 1: SELECT * FROM t WHERE 1
^
)
