Re: BUG #16698: Create extension and search path

What are then extensions.. They live in some sort of limbo.. as they don't
behave like a natural extension of the database... As they behave
differently (because they "require" public shema in path if extensions are
created while in public schema ).
If they would then this would work, but it doesn't.. and it requires fully
qualified names (OR public schema in set_path) which is annoying.

postgres=# CREATE DATABASE test;
CREATE DATABASE
postgres=# \c test
You are now connected to database "test" as user "postgres".
test=# SHOW search_path;
search_path
-----------------
"$user", public
(1 row)

test=# CREATE EXTENSION ltree;
CREATE EXTENSION
test=# CREATE SCHEMA foo1;
CREATE SCHEMA
test=# CREATE SCHEMA foo2;
CREATE SCHEMA
test=# SET search_path = foo1;
SET
test=# CREATE TABLE t(l ltree);
ERROR: type "ltree" does not exist
LINE 1: CREATE TABLE t(l ltree);
