Re: Can we go beyond the standard to make Postgres radically better?

The MySQL autocomplete is designed without context filtering. Maybe we can have this implementation too (as alternative)

so using all column names + all table names + aliases.column names (when we know defined alias)

Another idea about column excluding. Any implementation on the client side is very complex, because you need to parse sql. But maybe we can enhance SQL with some syntax.

SELECT ... and LAST optional clause can be HIDE, OR EXCLUDE NAME or EXCLUDE TYPE

SELECT * FROM postgistab HIDE TYPE LIKE 'wkb%'
SELECT * FROM postgistab ORDER BY ... EXCLUDE COLUMN LIKE 'shape%'

WITH x AS (SELECT * FROM xx)
SELECT * FROM x EXCLUDE COLUMN x1,x2

The column excluding should be separate *last* clase.

More with this syntax is less possibility of collision with ANSI SQL
