Old description:
> I have a question.
>
> It seems ST_SIMPLIFYPRESERVETOPOLOGY (from postgis, which documentation
> says it is performed by the geos module) sends varying data with some
> MULTILINESTRING inputs
>
> It also seems that the longer the MULTILINESTRING, the greater the chance
> of variation.
>
> My question: is this a bug or something to be expected ?
>
> example SQL : (run a few times, check that diff is sometimes not empty)

New description:
I have a question.
It seems ST_SIMPLIFYPRESERVETOPOLOGY (from postgis, which documentation
says it is performed by the geos module) sends varying data with some
MULTILINESTRING inputs
It also seems that the longer the MULTILINESTRING, the greater the chance
of variation.
My question: is this a bug or something to be expected ?
example SQL : (run a few times, check that diff is sometimes not empty)
{{{

ST_ASTEXT(ST_DIFFERENCE(A,A)) AS DIFF
