Everything should have an id, and combination tables like person-gene should
have the person id + the gene id.

I like this one too:
http://mogwai.sourceforge.net/erdesignerng.html
It does reverse engineering, but if you are creating a new model, that
capability is not a necessity.
Mogwai is not Postgresql specific, so you can use it with any db.

Hi,
If I have understood well
You have two options:
1. Person_gene (person_id pk, gene_id int)
Genes (gene_id serial pk, gene_type int)
Then for each gene_type separate table with gene_id int what is pk and
relates to genes... And other columns what describe that type...

I'm making a database which will store pseudo-genetic data. It's a basic

Interesting discussion.
The comparisons with timezones ends when it comes to exchange rates.
The rate at the time of transaction has to the stored (somewhere)

No way can be solved just by type

The only comparison I made with time and time zones was in how the
column type can be refined when it is created.

Some thoughts.
The current MONEY type might be considered akin to ASCII.
Perfect for a base US centric accounting system where there are
cents and dollars and no need to carry smaller fractions. As
discussed, there are some details
Martijn van Oosterhout developed tagged types back in 2005, looks like
it went nowhere. You can search for it, it was pretty interesting.
