Rollback with dropFunction

When performing rollbacks, Liquibase allows you to drop functions with or without quotes in the function name. Name Examples:

  • "FUNCTION1"()

  • FUNCTION1()

If you use double quotes like "FUNCTION1"(), the corresponding drop syntax should be DROP FUNCTION "FUNCTION1"() as well.
