The ST_Union accepts an array of geometries ( [geom1, geom2] ) in each row. What you want to achieve from my understanding is to do ST_Union of all the rows in the specified column, for that we have ST_Union_Aggr. In PostGIS when you are invoking ST_Union after group by, you are using [the fourth variant not the third](https://postgis.net/docs/ST_Union.html#:~:text=geometry%20ST_Union(geometry%20set%20g1field)%3B). -- This is an automated message from the Apache Git Service.
