Unexpected behavior of DROP VIEW/TABLE IF EXISTS

Hi,
I want to delete a table X, that may not exist, hence I execute

    DROP TABLE IF EXISTS X;

However, if X is a view, I get an error

    ERROR: "X" is not a table
    HINT: Use DROP VIEW to remove a view.
    SQL state: 42809

That is unexpected and also difficult to handle, if I want to be sure 
that I can delete all old tables *and* views called X, and create a new
view for instance with

    CREATE VIEW X AS ....

I cannot do that safely, because having both DROP commands would for 
sure cause an error and therefore a rollback.

What do you think, is it worth to create a patch to solve this issue, 
where a DROP TABLE does not fail, if the given name is actually a VIEW 
or vice-versa?

Best regards,
Peter
