For replication via pgadmin, I followed the steps in this [follow the link below]

Here I am facing the same problem as depicted in this site [Second one]. i.e.

Adding a new sequence:

      Right-click 'Sequences (0)' and select: 'New Sequence'

      Click 'Sequence' dropdown list item.

      [This step does not work for me, as I find at  this
point, there are

no sequence dropdown items so a sequence cannot be created at this point.

Otherwise if you have a sequence dropdown item, continue...]
