Schema: Wrong data types

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

Most RDBMS don't have too many data types, with PostgreSQL being an exception via its powerful EXTENSIONS system. Even so, using the correct data type has at least these benefits:

For example

CREATE TABLE transaction (
  -- [...]
  amount     TEXT NOT NULL, -- Amount is probably a DECIMAL or NUMERIC value, so why not use that?
  value_date TEXT NOT NULL  -- But it's a date, so why not use DATE or TIMESTAMP?
);
