  Lipgrate provides a declarative way to define your schema changes.

  === Column Definitions ===
  A column definition is a string with 'type:modifier1:modifier2'.
  Examples: 'string', 'text:notNullable', 'integer:unique'

  === Supported Data Types (SQLite) ===
  Affinity: TEXT, NUMERIC, INTEGER, REAL, BLOB
  Shorthands: increments, string, text, integer, boolean, blob, datetime
