Summary: PDO treats backslashes in pgsql passwords as escape
characters

New Comment:
So you believe that it is not PDO's responsibility to escape input
values before passing them to underlying functions?
That doesn't sound right.

This is due the libpq behavior. See

Description:
------------
When using a password containing a backslash to connect to PostgreSQL
database via PDO the driver appears to be treating the backslash as an
escape charcter.
The problem is not global to PDO since MySQL works as expected.
It is not global to libpq since PearDB and the psql command line tool
work as expected.
Further explanation in the comments in the test script.
Test script:
---------------
$host = 'localhost';
$database = 'imix';
$username = 'imix';
// Password is |\/|ix3dUp
/*
Works for MySQL - Doesn't work for pgsql - wireshark shows |/x3edUp
sent to server, error message shows password correctly
*/
$mysql_password = '|\/|ix3dUp';
/*
Doesn't work for pg - |/x3edUp still sent to server - error message
still shows password correctly - this is because \ is one of the two
chars escaped in a single quoted string
*/
// $password = '|\\/|ix3dUp';
/*
Works for pgsql, not for mysql - Error message on mysql attempt shows
two backslashes
Initial parse treats the first one as an escape, handing two to PDO -
pgsql driver seems to interpret the first remaining one as an escape
which really doesn't sound right ...
*/
$pgsql_password = '|\\\/|ix3dUp';
$mysql_connection = new PDO('mysql:host='.$host.';dbname='.$database,
$username, $mysql_password);
$pgsql_connection = new PDO('pgsql:host='.$host.';dbname='.$database,
$username, $pgsql_password);
Expected result:
----------------
I would expect the password as used for MySQL to work for both the
engines.
Actual result:
--------------
Test script as it stands executes without error.
