Name

postgis.backend — The backend to service a function where GEOS and SFCGAL overlap. Options: geos or sfcgal. Defaults to geos.

Description

This GUC is only relevant if you compiled PostGIS with sfcgal support. By default geos backend is used for functions where both GEOS and SFCGAL have the same named function. This variable allows you to override and make sfcgal the backend to service the request.

Availability: 2.1.0

Examples

Sets backend just for life of connection 

set postgis.backend = sfcgal;

Sets backend for new connections to database 

ALTER DATABASE mygisdb SET postgis.backend = sfcgal;
