Hi Hugh,
Stupid me on forgetting the double braces. How can I change the
default srid from 4326 to something else? I just want a 2d Cartesian
coordinate system (my data isn't WGS 84). Although it seems I can
change the srid with st_setsrid, ttlp will throw the same error as below
when I try to load my non-4326 data (even with the extra braces). - Erich

Hi Erich,
You need to have double opening and closing braces around the

Hi Hugh,
Awesome! However, I tried adding a single triple as follows and
got an error. Am I missing something?

Are there any plans to support other geometries like POLYGON besides
POINT in Virtuoso?
As per, "9.34.3. Geometric Objects - Only the 2D point is
supported." at
