Name
postgis.gdal_datapath — A configuration option to assign the value of GDAL’s GDAL_DATA option. If not set, the environmentally set GDAL_DATA variable is used.
Description
A PostgreSQL GUC variable for setting the value of GDAL’s GDAL_DATA
option. The postgis.gdal_datapath value should be the complete
physical path to GDAL’s data files.
This configuration option is of most use for Windows platforms where GDAL’s data files path is not hard-coded. This option should also be set when GDAL’s data files are not located in GDAL’s expected path.
