   @iajoiner Ident is currently a "universal" struct for capturing any 
identifier.
   
   I think adding limits will require capturing the different subtypes of 
Ident, as the length limits may vary.
   
   Postgres, for example, has:
   Table name -> 63 characters
   Column name -> 59 characters
   
   I think that this kind of rule is about enforcing SQL semantics, which the 
crate tries to avoid. 
   See `Syntax vs Semantics` in README.
