SQL Bug?

От

I'm far from an SQL expert, but...

select field1 from table1 where table2.field2 = table1.field3;

This query, which uses tables in the where clause that aren't in the list
of tables, actually does what one would sorta expect in PostgreSQL, but
isn't it a bug for it to do that?...

Not that I mind, since it's what I accidentally coded anyways.

It is a feature we have not removed.
