(I have a really old Mac with the 9.6.1 version installed).
Yes.
The CLI client psql is based on libpq and from here:
"If you want to use psql to connect to several servers of different major versions, it is recommended that you use the newest version of psql. Alternatively, you can keep around a copy of psql from each major version and be sure to use the version that matches the respective server. But in practice, this additional complication should not be necessary."
If you have a new version of psql available connect to the 9.6.1 instance to verify.
Thank you.
Ill try to get the new version and build it.
