Hi Chuck, I’ve also seen your post about subclassing JDBCPlugIn, which I’ll try shortly, but...

This is in a migration’s upgrade() method, after I CREATE EXTENSION and ALTER TABLE: // Get the model EOModel model = ERXModelGroup.defaultGroup().modelNamed("Ident"); // Get jdbc2Info dictionary from connectionDictionary NSMutableDictionary<String, Object> overrides = ((NSDictionary<String, Object>) model .connectionDictionary().valueForKey("jdbc2Info")) .mutableClone(); // Build the value we want for the typeInfo.citext key NSDictionary<String, Object> citext = NSPropertyListSerialization .dictionaryForString("{defaultJDBCType = (\"OTHER\"); createParams = \"0\"; maxScale = \"0\"; minScale = \"0\"; isNullable = \"T\"; isSearchable = \"T\"; precision = \"0\"; }"); // Add the citext entry to overrides overrides.takeValueForKeyPath(citext, "typeInfo.citext"); // Apply the overrides EODatabaseContext.forceConnectionWithModel(model, overrides, editingContext); Any comments on the safety/desirability of this approach, or where it sits on the scale of awful hacks?
