Name

postgis.enable_outdb_rasters — A boolean configuration option to enable access to out-db raster bands.

Descrizione

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.

[Note]

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

[Note]

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

Disponibilità: 2.2.0

Set and reset postgis.enable_outdb_rasters for the current session.

SET postgis.enable_outdb_rasters TO True;
SET postgis.enable_outdb_rasters = default;
SET postgis.enable_outdb_rasters = True;
SET postgis.enable_outdb_rasters = False;
                

Set the default for all new connections to a database.

ALTER DATABASE gisdb SET postgis.enable_outdb_rasters = true;

Set the default for the whole database cluster. This requires superuser access. Also note that database, session, and user settings override this.

This example writes the setting to postgres.auto.conf.

ALTER SYSTEM SET postgis.enable_outdb_rasters = true;

Reload the PostgreSQL configuration so the changed setting is applied.

SELECT pg_reload_conf();
