[postgis-users] ST_Split returning multipart
Hi all. I have a linear network as a single multilinestring. I need to cut it in separate subnet using a point layer. ST_Split dos the job, but it returns the subnet split into multipart, and I do not have an id to put them together. I cannot find a way to split the original network retaining each subnet as a single object. Am I missing something?

[postgis-users] spatial_ref_sys not populated after upgrade
Hi all, after an upgrade of Potsgres and Postgis the spatial_ref_sys table is created, but not populated. I kind of remember having the same issue, but I cannot find traces in my notes nor on the internet. Any hint of what can have be gone wrong? Cleanest way to fix this?

I get the error when I import from QGIS (which uses GDAL behind the scenes):
ERROR: function addgeometrycolumn(unknown, unknown, unknown, integer,
unknown, integer) does not exist
RIGA 1: SELECT AddGeometryColumn('public','world_simpl','geom',3857,...

NOTA: No function matches the given name and argument types. You might
need to add explicit type casts.
This on:
PostgreSQL 13.0 (Debian 13.0-3) on x86_64-pc-linux-gnu, compiled by gcc
(Debian 10.2.0-13) 10.2.0, 64-bit
Whereas exactly the same thing on:
PostgreSQL 11.9 (Debian 11.9-0+deb10u1) on x86_64-pc-linux-gnu, compiled
by gcc (Debian 8.3.0-6) 8.3.0, 64-bit
works smoothly, as has always done.

Hi all, we noticed two strange things in the behaviour of ST_IsValid: * repeated vertices are not considered invalid * in case of multiple intersections on a same polygon, only the first one is reported. Is there an explanation for this?

Hi all. More info: the lack of SRID and geometry type in the geometry_columns happens only for the tables created by PostGIS functions (e.g. st_union, st_convexhull, etc.). Is this a known issue?
