Description:
------------
If a database contains tables with the same name in different schemas,
requesting the meta data for this table returns a mix for all fields in
all that tables.
Related to bug #35996 http://bugs.php.net/35996

Reproduce code:
---------------
mydb=# create schema a;
mydb=# create schema b;
mydb=# create table a.test(id int, field1 text);
mydb=# create table b.test(id int, field2 text);

In PHP connect to `mydb' with user `a' (search_path will be set to schema a) or with different user and say "set search_path = 'a';". Use pg_meta_data('test') for get table metadata.

Expected result:
----------------
a.test metadata:
 attname | attnum | typname | attlen | attnotnull | atthasdef |att...
---------+--------+---------+--------+------------+-----------+-----
 id      |      1 | int4    |      4 | f          | f         |    0
 field1  |      2 | text    |     -1 | f          | f         |    0


Actual result:
--------------
mix of a.test and b.test metadata:
 attname | attnum | typname | attlen | attnotnull | atthasdef |att...
---------+--------+---------+--------+------------+-----------+-----
 id      |      1 | int4    |      4 | f          | f         |    0
 id      |      1 | int4    |      4 | f          | f         |    0
 field1  |      2 | text    |     -1 | f          | f         |    0
 field2  |      2 | text    |     -1 | f          | f         |    0

Marcus, this ought to be simple fix. Just add an optional parameter to pass the schema with and use that if passed..?

Bug #35996 had some sort of improved query to get the metadata.
As I don't use pgsql, I don't want to mess with the code either. :)
