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.

Not to the SQL interface but some of the structures used are different
-- just as they may change when using different operating systems.
