Doesn't quite make sense to me why translating before ST_Union would cause
distortion if you are translating all the same amount.
What is the SRID of the data you are translating and what does your
translate query and union query look like?

Subject: [postgis-users] ST_Translate
I've imported a shapefile that requires six rows in the table.
When I translate that shape, of six rows, to another location the shape
When I collect the six rows by using ST_Union, then translate the single row
to the new position, there is no distortion.
Is there a method of using ST_Translate, without also using ST_Union, and
still avoid the distortion of the shape??
I need the geometries of the shape separate to be able to identify the
parts of the shape I need. I seem to lose this informaion when I employ
