I guess you have two options:
1) clip and union your tiles BEFORE computing the quantile
2) use the ST_Quantile variant taking table and column names. I don't know if
these function aggregates the results though.

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 :-)

This is done to optimize data transfer and overall performance when doing
map rendering, we just get the

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.
