Operating system: debian
PHP version:      5.3.2
Package:          PostgreSQL related
Bug Type:         Feature/Change Request
Bug description:pg_escape_string() mishandles \

Description:
------------
My understanding of pg_escape_string() is that it will escape only those
characters that require escaping by the postgresql database.

Using standard_conforming_strings=on in postgres (8.2.4) a "\" (backslash)
character is just a backslash character, not a special character requiring
escaping.  Therefore, I do not think pg_escape_string('\') should return
'\\' but rather '\'.

The only way I can see to enter a single backslash character is to use the
E('\\') syntax but I should not have do so.


Test script:
---------------
<?php
print pg_escape_string(' \ ');
?>



Expected result:
----------------
should return ' \ '

Actual result:
--------------
returns ' \\ '
