I use the attached patch for this purpose, that slightly simplifies
things and covers all the other binaries:
git apply .../install-vrunner.patch
CPPFLAGS="-DUSE_VALGRIND -Og" ./configure --enable-tap-tests
--enable-debug --enable-cassert && make && make check
`make check-world` is possible too, with
src/bin/pg_ctl/t/001_start_stop.pl disabled (removed).
