Hi Andrea,
You could use a PLPGSQL function to catch error for curved geometries and
return the geometry itself in case of error.
Then, either you put all your generic code in this function, or you just
write a wrapper around st_simplify and call it from your SQL code,
according to your needs.

Putting an exception block will slow down your function.
You can put an exception in any plpgsql function.
So you only need the right to create a plpgsql function.

Ah ha, looks like exactly what I wantedI did search for all function
names containing curves,
it did not occur to me to search for arc :-)

Looks like there is still a wrinkle... one can build compoudcurve without
any arc in it, ST_HasArc will
return false, but ST_Simplify only che

Ah, but I'm not really interested in this one.

Hi,
just to be on the safe side, I've opened both:
http://trac.osgeo.org/postgis/ticket/3112
http://trac.osgeo.org/postgis/ticket/3113
