Yes, creating a trigger after a COPY or \copy would be an option.

Alternatively you could use a GDAL OGR VRT driver [0], and use
ogr2ogr to directly import the geometry without needing to store in
the database the X and Y values at all. It is just a matter of
correctly setting the GeometryField attribute:

<GeometryField encoding="PointFromColumns" x="coordinateX" y="coordinateY"/>
