I'm not sure of the compatibility with Debian 10, but this should be either one
of these commands:

  pcs resource promotable pgsqld pgsqld-clone meta notify=true
  pcs resource master pgsqld meta notify=true

If you want to use this two step syntax, see the fine manual of pcs or eg.:

  https://clusterlabs.github.io/PAF/Quick_Start-Debian-9-pcs.html#cluster-resources

Arguments "clone" and "master" have two different meanings. A "clone" ressource
is a simple one-state ressources that must be cloned and start on a various
number of node. Think httpd. The clones can either be stopped or started.
Pacemaker doesn't expect to be able promote a clone.

The "master"/"promotable" resources are an extension of clone ressources with an
additional state: stopped, started and promoted. In the last versions of
Pacemaker, we talk about clone -vs- promotable clone.

Under Debian 10, you can create your resource with the flag "promotable".
