Maybe as shown here:

https://www.repmgr.org/docs/current/configuration-file-optional-settings.html

"
pg_bindir (string)

Path to the PostgreSQL binary directory (location of pg_ctl,
pg_basebackup etc.). Only required if these are not in the system PATH.

[...]

Debian/Ubuntu users: you will probably need to set this to the
directory where pg_ctl is located, e.g. /usr/lib/postgresql/9.6/bin/.
"

Also looks to me like there is version 5.4 installed somewhere else that
is being picked up. I would do a find to locate out all the repmgr
instances installed.
