Are domains user defined types? That they seem to be based on what I see
on the docs.

Any drawbacks to using them?

Right now I have a new database I am making and wanted some consistency
accros some tables. Currently I used inheritance to enforce the consitency
since a good number of fields needed to be common among the tables AND the
inheritted tables are basically a supperset of the data, so some times I
would want to access the inheritted tables and other times the parent/main
table.
