Hi,
just a quick chip-in from someone who is totally ignorant of the
Postgres data model:

I don't know the relation between your "linestrings" and what I know as
segments. Just wanted to say that I regularly create multiple ways
sharing the same segments (e.g. one being a road, one a tram running on
that road). I guess this will automatically separate in multiple
"linestrings" and thus not pose a problem?
Bye
Frederik
