[postgis-users] ERROR: mixed dimension geometries

[Pierre Racine]

Hi,

What is the meaning of:

ERROR: lwcollection_construct: mixed dimension geometries: 0/2
SQL state: XX000

I get this when I do ST_Intersection() on two tables. Both tables contains only one geometry. ST_Dimensions give 2 for both.

How can I fix it?

I tried ST_Buffer(geom, 0) without success.

Thanks,

Pierre
