Yes. Install exim4-daemon-heavy first -- nothing should change.

Now that depends on what kind of lookups you want to do. Generally
speaking, in ACLs you use
condition = ${lookup pgsql....}
(see
http://exim.org/exim-html-4.40/doc/html/spec_9.html#SECT9.17)
If you describe in more detail what you want to do, I'm sure I and
others can help you with the specific problem you're facing.
