Use a different Date data type
PLEASE backup your database before testing this commit, and report any migration issue. In postgresql, we use timestamp with timezone. In sqlite3 we use REAL (the date is expressed as julianday) This requires a migration of the muclogline_ table: In postgresql it’s pretty simple, we convert all the integer into timestamps With sqlite3, we actually rename the table, create the new one with the correct type, then copy everything to the new table, with a conversion function for the Date_ column, and then we delete the old table. fix #3343
