Right --- according to our normal terminology, b.mytable is *not* visible,
because it is masked by a.mytable being ahead of it in the search path.
You'd have to write a qualified name to get at b.mytable.
You can write, eg, "\dt *.mytable" or "\dt *.*" if you would like it to
show tables that are not visible according to this rule. Without a
dot in the pattern, \dt shows only visible tables, ie only the ones
you could name without putting a dot in the name.
