Hey,
you could use postgres windows function and group by on parcel_id,
coverage_id.
If using Union, overlapping polygons while be merged, and non overlapping
will only be grouped into multi or geom collection.
You might struggle to keep the id.

Hi all,
I have a table including FID, parcel_id, coverage_id and geom. I want to find
those polygons which have a partial intersect with the same parcel_id and
coverage_id and union the intersected ones as One polygon. For example if I
have 6 polygons with the same parcel_id and coverage_id
