Why are you using MAX()? That won't work at all. Perhaps you need to
look up the documentation for nextval and currval. In particular, that
second query should be:
insert into entity_phone select currval('entity_id_seq'),'610 495 5000';
Also, I'm not sure if inheritance works quite the way you think in the
example you give, though other people may correct me on that.
Hope this helps,
