I have never seen this done before, but it seems like it is supposed to work
from reading the manual.

I want to be able to get a table name from another table and use it in the
from clause of a select.

Something like

SELECT * FROM (SELECT name FROM bar WHERE conditions) AS b WHERE b.condition
= xxx;

which translates to something like

SELECT * FROM Dealer AS b WHERE b.zipcode = 12345;

The translated version works but the SELECT in FROM version reports that
b.condition does not exist.

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
