You're welcome.

This is intentional behaviour. The graphical tools allow you to create
object by hiding you from the details of the SQL queries required. This
includes quoting identifiers.
The Query Tool on the other hand is designed to allow you to write and
test arbitrary SQL queries, often before using them in your own repports
or applications. We intentionally do not modify the SQL you write here
in any way, otherwise you might easily run into unexpected problems when
you move your work into your own code (for example).

As I noted above, the query tool is designed to allow you to execute
arbitrary SQL queries on the server. Depending on the schema search
path, you may need to prepend the schema name to some objects, however
this is no different from how it would work in psql or any other
application. Whilst technically we could set the search path based on
the treeview object selected at the time the window is opened, this
strikes me a being a bad design (breaking the principle of least
surprise) as it would mean that the queries you have written suddenly
only work when you've opened the query tool from a specific place. That
would certainly cause me more problems than it would ever resolve, as
well as most other users I suspect.
I would suggest simply modifying the search path in the first statement
of your query if that is important to you.
