Indeed, I noticed this when I did pgxs;-) It is on my todo list for 
postgresql, but I haven't had time much time this year to contribute 
anything.

The reason it was not included at first is that it seemed to me that 
selftests require a temporary installation which make sense easilly when 
building from sources, but I was not sure about what would be really 
needed for the feature out of the compilation tree (special conf files, 
diff/comparison commands...). I was planning to investigate the details, 
but if the pg_regress command is enough, that was a little bit stupid of 
me not to do it directly. ISTM that the pg_regress command is not compiled 
by default, only under "make test", so it should be added to the default 
compilation?
