Description
I'm merging two geometries into one using st_union then st_difference with third geom which is epsg:2180 extend to get a mask. Union returns one polygon with shape of joined two geoms but difference produces hole in shape of one of joined geometries. If I add st_buffer everything is ok.

Without the full sequence of SQL to go w/ the table, and helpfully a picture of the inputs and expected outputs, this is going to languish.
