Description:
------------
Hello,

I have the following script:

pg_query("DROP SEQUENCE IF EXISTS test_seq;");

Have also tried:

pg_query('DROP SEQUENCE IF EXISTS "test_seq";');

Both issue warnings:

E_WARNING: pg_query(): Query failed: ERROR:  relation "test_seq" does not exist 
in /home/keiouu/tikapot/framework/databases/postgres.php on line 64
Exception 1!


Which would be fine but I have set:

pgsql.ignore_notice = 1


A phpinfo confirmed that it is set.

As there is no easy way of seeing if a sequence exists (that I know of) I don't 
believe any warning should be issued.

Test script:
---------------
pg_query("DROP SEQUENCE IF EXISTS test_seq;");

Expected result:
----------------
Nothing

Actual result:
--------------
E_WARNING: pg_query(): Query failed: ERROR:  relation "test_seq" does not exist 
in /home/keiouu/tikapot/framework/databases/postgres.php on line 64
Exception 1!
