Mariano, I made my own loader and patches packages for loading Glorp+PostgresV2 into Pharo 1.1rc2. Both can be found at http://www.squeaksource.com/ADayAtTheBeach GlorpPostgreSQLPharoLoader-SvenVanCaekenberghe.3.mcz GlorpPostgreSQLPharoPatches-SvenVanCaekenberghe.1.mcz All PostgresV2 tests succeed, as do all GlorpTest-DBTests. The GlorpTest package has the following result: 844 run, 838 passes, 0 expected failures, 4 failures, 2 errors, 0 unexpected passes Failures: GlorpSelectCommandTest>>#testExecute GlorpUnitOfWorkTest>>#testRollbackOneToManyAfterAdd GlorpDateTest>>#testDate GlorpRowMapForMementosCollectionTest>>#testRBSmallDictionary Errors: GlorpManyToManyDBTest>>#testReadNodeAndDeleteChildWithSaveAndContinue GlorpObjectMappedToImaginaryTableTest>>#testReadBackEntireExample My own code runs fine though. I hope you consider my patches, thanks, Sven BTW: the original #timestampWithTimezoneConverter simply could never work: it expects a +/- sign inbetween the timezone's offset's hour and minute fields ! it falls out of the tests because only timestamo without timezones are used.
