That's part of avoiding premature optimization. Any initial SQL backend
should have a very-low-level layer which deals with actually
communicating with the database and a slightly-higher-level layer which
performs as generic a SQL query as possible (no proprietary extensions).
  Only when the first pass is complete will it [hopefully] become
obvious whether or not performance issues require use of DB specific
extensions.
