[web2py] db table reference syntax

[Alex Glaros]

what  is the syntax for renaming a reference field in order to avoid 
duplicate names in a table?

example:

db.define_table('PersonSkill',
        Field('*id*','reference Person'),
        Field('*id*','reference Skill'),
        Field('YearsOfExperience','integer'))

The "id" field name would be duplicate because it is the same spelling in 
Person Table and Skill Table.

Also, does web2py reference field work in Postgres?

thanks!
