I have a versioned GDB (Postgresql) and I have versions DEFAULT-> A -> B. Version A modifies two poly lines and version B modifies one of the two that is modified in version A. In ArcMap, even though I have "List by source" selected and have selected the source (which also shows the selected version), I do not get "Post" nor "Reconcile" buttons enabled in the versioning toolbar when either version A or B is selected. Am I missing something or this is a bug?
For reference, I am using ArcGIS Desktop 10.3 with all patches installed as of now.
