Cannot create a Geo secondary

Summary

When I try to use https://gitlab.com/gitlab-org/charts/gitlab/-/blob/master/examples/geo/secondary.yaml, I get an error:

$ helm template gitlab . -f examples/geo/secondary.yaml --set certmanager-issuer.email=me@example.com
Error: template: gitlab/charts/gitlab/charts/geo-logcursor/templates/deployment.yaml:24:28: executing "gitlab/charts/gitlab/charts/geo-logcursor/templates/deployment.yaml" at <include (print $.Template.BasePath "/configmap.yml") .>: error calling include: template: gitlab/templates/_helpers.tpl:207:21: executing "gitlab.psql.port" at <.Values.psql>: wrong type for value; expected map[string]interface {}; got interface {}

@WarheadsSE noted that this was introduced in 12.10 by !1212 (merged).

Tests like !1268 (merged) may have caught this 😉
