[Modeling-users] varchar and text

[Ernesto R. <er...@si...>]

Going thru the PostgreSQL doc version 7.3.2 it says:
* varchar w/o upper limit is not standard SQL
* text is postgres specific
* varchar w/o limit and text have no performance penalities compared with
varchar with limit
* a lot of modern dbms systems support unlimited text.

What's about mySQL? I would like to see if the the width requirement of
varchar would be loosened (perhaps a warning, or ignored). I don't know how
other database system treat this.
