title: How does Liquibase map boolean for oracle?
body: <p>Known fact: Oracle does not support Boolean natively.
  So it is recommended to use either Char(1) or Number(1) and then creating a constraint to limit the values to Y/N or 0/1.</p>
  
  <p>That being said.
  When creating a boolean for an oracle database, Liquibase creates a number(1).
  Does anyone know if it also creates the database constraints?
  i.e.: "check (bool in (0,1))"</p>
