inaccessible via SSH

[gpettey]

repmgr is reporting inability to use SSH. Using the same key as in ssh_options configured, I verify that SSH works. The output "bash: repmgr: command not found" makes me think it is not using an interactive/login shell and therefore not getting its PATH set appropriately, as I can reproduce the error message by adding "repmgr" as the command directly to ssh.

I am using version 5.2.1 on RHEL 8 from the 2ndquadrant RPM repository.

Commands executed via ssh don't normally run in a login shell (similar issue occurs with commands executed as a cronjob).

The preferred solution is to set pg_bindir in repmgr.conf (on all nodes) to the PostgreSQL path (e.g. pg_bindir=/usr/pgsql-11/bin/); in the unusual situation that repmgr is installed in another location, repmgr_bindir can be used. This path will be prepended when executing repmgr remotely.

That works. Is there a reason why it isn't included in the basic sample of https://repmgr.org/docs/current/configuration-file.html? Seems like an important setting to call out as required.
