Also another comment for your transrotate function: you can use 1 call
to ST_Affine, rather than 3 indirect calls with
"st_rotate(st_translate(st_rotate(". You just need to wrangle the
trigonometry in the affine transformation matrix correctly.
I have an enhancement for a st_rotate with a point of origin in trac,
where you can see how to use ST_Affine for this purpose:
