The other disadvantage I have noticed is that you can't override operator behavior of text but you can for varchar.
So I have been able to override the case sensitivity of varchar fields (which is annoying when working with MS Access etc) simply by changing the way LIKE, = > etc. are handled for varchar. Since text is defined in pg_catalog, it doesn't seem possible to override it or at least haven't had any success with that. Maybe I am missing something.
Thanks,
Regina

One disadvantage is that if you are using MS Access as a front-end via
ODBC / linked tables, you can not do joins on fields set as text (in
queries, etc)

Don't you mean VARCHAR(n) will be slightly slower on UPDATES.
