Comment (by David Sanders):

 I need to clarify an incorrect assumption I was making in my earlier
 comment.

 COALESCE() is acceptable for use in generated fields & function indexes.
 This is because it's not a "real" function, it's an expression.

 This means that Paolo's proposal to make `Concat()` on Postgres more like
 it does on SQLite an acceptable change keeping behaviour consistent.
