Usually PGXS loads after setting all the environment variables, though I suspect that it wouldn't have any side effects
toset regress_opts afterward. Also, there is no MAJORVERSION in earlier versions, so module authors would have to work
aroundthat. 

Basically though, you're asking all third party module authors who depend on plpgsql in their code and/or tests to
modifytheir makefiles and release new versions to work around something that pg_regress could have fixed internally in
1-2lines of code and be done with it.
