Comment:

 It turns out that #11900 is indeed not needed.

 I can not reproduce any of the errors you mention.

 Moreover, the file "sage/devel/sage/databases/database.py", for which you
 reported an error, does not exist in vanilla sage (not in 4.7.2 and not in
 4.8.alpha3).

 Did you test other patches before returning to vanilla 4.7.2? Namely, when
 a patch changes a module from python to cython, and one wants to remove
 the patch, then it is often needed to also remove any reference to the
 cython module in `build/sage/...` and in `build/*/sage/...`. For example,
 when I had #11115 applied and want to remove it again, then I would do `rm
 build/sage/misc/cachefunc.*` and `rm build/*/sage/misc/cachefunc.*`.
