Hi,

I have installed PG v9.6 / v9.5 , if we run pg_resetwal from v10 
binaries against data directory of v9.6/9.5 ,getting this error -

centos@centos-cpula bin]$ ./pg_resetwal -D /tmp/pg9.6/bin/data/
pg_resetwal: pg_control exists but is broken or unknown version; ignoring it
pg_resetwal: could not open directory "pg_wal": No such file or directory
[centos@centos-cpula bin]$

Steps to reproduce-
installed PG v9.6
installed PG v10
go to bin directory of v10 and run pg_resetwal , provide -D = data 
directory of v9.6.
