Oh, and of potentially more significance: after maintainer-clean and re-configure, make fails with In file included from jsonpath_gram.y:24: ../../../../src/include/utils/jsonpath_scanner.h:25:33: error: utils/jsonpath_gram.h: No such file or directory I first thought this was a problem with insufficient dependencies allowing parallel make to do things in the wrong order, but the problem repeats even without any parallelism. It looks like the dependencies have been constructed in such a way that if the symlink at src/include/utils/jsonpath_gram.h exists but the underlying file does not, nothing will make the underlying file. This is pretty broken; aside from this outright failure, it also suggests that nothing will update that file if it exists but is out of date relative to its sources. Please make sure that the make rules associated with these files look exactly like the previously-debugged rules for existing bison/flex output files. There are generally good reasons for every last bit of weirdness in those. regards, tom lane
