Yes, generalny i use 11.4 bins, but libpq, dump, dumpall, restore and psql are old ones.
Nów I have made the test with original 9.5.16 to 10.2 and it succeeded. If it is the binary version problem, I´m a little bit surprised, because I havent´s seen it in a code.
If it is the only bug, that you have, so please do not change code, due to my problem :-). I ´ll do my test one more time, this time with 11.2 binaries. Will let you then know.

If you're not certain, run each program with the --version switch
to find out. But pg_upgrade should be refusing to use pg_dump
et al that aren't from its own major version.
