Table Alias

Through the help of some inexperienced embedded SQL coders I stubled across
a strang Postgres quirk. I am wondering if this is normal or if I have
configured something incorrectly. Here's the situation...

The following two selects return very different values:

select b.name from foo f, bar b
where f.foo_id = 1
and f.bar_id = b.bar_id;

select bar.name from foo f, bar b
where f.foo_id = 1
and f.bar_id = b.bar_id;

The first returns the rows in the name column of bar that have the same
bar_id as the foo record with foo_id = 1. (Correct)

The second returns all rows in the name column of the bar table. (?)

I am quite aware that if you declare an alias for a table that you should
use it, but I am very surprised that the select becomes unqualified if you
mistakenly use the full table name. Is this normal behavior?

Thanks!
Darrin
