Some evolutions are safer for PPD like > byte -> short -> int -> long > float -> double > conversions between char, varchar and strings > For all other conversions we can disable PPD for that specific column that has evolved by returning TruthValue.YES_NO -- This message was sent by Atlassian JIRA (v6.3.4#6332)
