Sorry, I should have been a bit more specific! I would like some kind of
option to disable all cases of adding tables to FROM clauses by
implication. The main issue I have with this feature is it is more likely
to be used (by me) by accident (as a result of a typo), and consequently
introduce very strange results.

I am unaware (yet? ;-}) of any other non-SQL features in PostgreSQL that
are likely to cause me the same level of concern. Adding tables to a query
seems very dangerous: some people might, for example, expect an automatic
natural join on primary/foreign keys if you add a table.
