Opteron was not publicly accessible 7.3 release was made, thus 7.3 does not support that platform. 7.4 seems to be functional on that processor per reports so it will probably be a supported platform for this release. Download 7.4 beta 2 and run regression tests on those platforms. Report back any issues or successes. 7.4 Release candidates will come with a call for reports on platforms that pass the regression tests which are used to make up the supported platform list. > difference between the 32-bit and the 64-bit versions, if there is some > differences in semantics or something like that or it's just the > implementation and the application features are "transparent" for the user. Not to the SQL interface but some of the structures used are different -- just as they may change when using different operating systems.
