Hi list,
I'm running into this issue with GeoServer 2.8.2/GeoTools 14.2:
https://osgeo-org.atlassian.net/browse/GEOT-5079
This happens when the Postgres user used in the GS/GT datastore doesn't
have permissions to read from the geography/geometry_columns tables, or if
a record for the geom doesn't exist in those tables. GeoTools falls back to
trying to use a non-existent DIMENSION() function to get the number of
coordinate dimensions from a sample geometry. Testing with GeoServer, every
configured layer throws this error during startup, which causes several
minutes of delay.
Although this is a database configuration problem, GeoTools should fall
back to using a working function to determine dimensionality. Based on the
contents of geometry_columns.coord_dimension, the function should be
ST_NDims. I can make a quick PR, just following contributor protocol here,
especially since I don't see updates from this JIRA ticket coming through
on the mailing list.
Also, I can't figure out a good solution for a test case here, and it's
such a small change I'm not sure if it needs one? Any suggestions?
Thanks,
Shane
