Bug in geometry_columns view — at Initial Version

Reported by: jonochang Owned by: pramsey
Priority: medium Milestone: PostGIS 3.1.12
Component: postgis Version: 3.4.x
Keywords: Cc: jonochang

Description

We have encountered a bug in the geometry_columns view where the subquery which returns ndims for a constraint assumes a certain format that does not work with contraints used by other libraries.

See this section here: ​https://github.com/postgis/postgis/blob/8a41ae8f4bf7fe533f16bda1a998e61a460ed211/postgis/postgis.sql.in#L6422

and an example constraint here in the attached test-schema.sql: 

  81   │     job_schema_version integer DEFAULT 1,
  82   │     CONSTRAINT valid_queues CHECK (((array_ndims(queues) = 1) AND (array_length(queues, 1) IS NOT NULL))),
  83   │     CONSTRAINT valid_worker_priorities CHECK (((array_ndims(worker_priorities) = 1) AND (array_length(worker_priorities, 1) IS NOT NULL)))
  84   │ );

An example output from the attached failing query test-query.sql is here: 

                                                                                                                                                                              postgis_full_version
