Description:
------------
This is the code-snipped:

$limit = "5";
print_r( array(pg_escape_literal($limit) , gettype(pg_escape_literal($limit))) );

And it prints:

[false,"boolean"]

However, the documentation says, that "pg_escape_literal()" returns only strings.
I'm not sure if it's a php-bug, or a documentation-error.

Documentation-Page:  http://www.php.net/manual/en/function.pg-escape-literal.php

Test script:
---------------
$limit = "5";
print_r( array(pg_escape_literal($limit) , gettype(pg_escape_literal($limit))) );


Expected result:
----------------
["'5'","string"]

Actual result:
--------------
[false,"boolean"]
