Yes, I want to add a point in existing Postgres table but via qgis (digitize it) by adding exact coordinates (XY) values. In ArcGIS, I can do that by using Absolute XY (F6). I know how to do it in qgis by using a plugin name LatLon Tools. The issues is those latlon tools cannot be used to add coordinate when when the data is called from the Postgres database.
