Since the structure of the data type conversions has changed from 2.x to 3.x, and now data types are registered using the Service Locator pattern (lines 25 - 30 of DataTypeFactory), it’s not so easy to determine the various LiquibaseDataType to DatabaseDataType mappings.
It would be great if there were a command line parameter or command that would dump the runtime data type conversion matrix in some legible format (HTML,XML,JSON,etc).
