Hi all,
I need to convert a lot of Box3D geometries to TIN geometries. Is there a way
in PostGIS to do this without specifiying each triangle and vertex for the new
TINs explicitly? Idealy, I would just be able to issue a simple update
statement without needing to think about vertex order and
order :-/

Hi Regina,
It might not really fit the book, because it's not exactly GIS, but our
PostGIS use case is certainly an interesting one as well: As a software

Yes, you can. But you have to make sure the *same* version of PostGIS is
available in the target database.

Hi,
I am in the process of evaluating an upgrade from Postgres 11 to 12 and
PostGIS 2.5 to 3. For one central query in my application the same plan
is executed in slightly different ways in the older PG11/PGIS2.5 setup
compared to the new one. I wonder if anyone has some insight why this

fits indeed better to the initial observation that PostGIS 2.5

3.0 is faster if &&& is not used, but only because the 2.5 queries get
much slower.

I use Postgres 9.4 and PostGIS 2.1 to represent about 13.000.000
vertices in a 3D space (growing). Many points are connected in tree
structures of varying size, often around 5000 nodes per tree. Therefore,
we use single edges to represent them in our table. My aim is to have

Hi William,
Did you run VACUUM ANALYZE on on the PG 9.4 table (after you imported
the data)? This would be required to have up-to-date statistics which
the query planner uses to e.g. decide if using an index would improve
query time.
And what is the query plan for your query (EXPLAIN ANALYZE)?

Hi all,
I hope this is the right place to ask, please let me know if it isn't.
PostGIS is involved in this problem, but I am unsure whether it is
