Yep, "git clean -dfx" did the job. "make distclean" didn't, btw.
I've had "src/backend/catalog/schemapg.h" file in source tree
generated with "make submake-generated-headers" on REL_13_0.
It were not shown with "git status", therefore I didn't notice its
existence. It were not deleted neither with "make distclean", nor with
"git clean -dx" I tried before. Only "git clean -dfx" deletes it.

Thank you for the suggestion, Tom. You've saved my sanity.
