Thanks to all of you very much for your insightful replies!
The circles are computer-generated with 15-20 points (I should've mentioned
that from the beginning).
I very much like the compactness-approach as well as the LineToCurve.
I will try out these approaches and let you know about my
Hey,
your question is a little bit un-precise.
If you try to find circle that have been drawn by a CAD program for
instance (perfect circle),
you can use ST_LineToCurve().
If you are trying to detect polygons that look like circle (maybe the
border is very close to a circle, but overall it is
I have many different polygons in my database and would like to know if
there's any way to find out if a polygon has the shape of a circle. I
searched both on Google and in the Postgis documentation but couldn't find
someone with the same question.
The lines joining the vertices of a

if there's any way to find out if a polygon has the shape of a circle.
You could try to compute compactness for the shapes.
See e.g.
