postgis.enable_outdb_rasters

Description

A boolean configuration option to enable access to out-db raster bands. This option can be set in PostgreSQL's configuration file: postgresql.conf. It can also be set by connection or transaction.

The initial value of postgis.enable_outdb_rasters may also be set by passing the environment variable POSTGIS_ENABLE_OUTDB_RASTERS with a non-zero value to the process starting PostgreSQL.

	Even if postgis.enable_outdb_rasters is True, the GUC postgis.gdal_enabled_drivers determines the accessible raster formats.

	In the standard PostGIS installation, postgis.enable_outdb_rasters is set to False.

Availability: 2.2.0
