I'm new to GIS and tile servers. I've installed TinyOWS pretty successfully except for what looks like to be some dependency issues. I have installed PostGIS and also PostgreSQL. PostGIS is supposed to come with raster and topology support, so I assume it is already installed but not enabled. Anyway I can't find any good online resources for this so I need some help.
Here is my error:
NOTICE: Function postgis_gdal_version() not found. Is raster support enabled and rtpostgis.sql installed? NOTICE: Function postgis_topology_scripts_installed() not found. Is topology support enabled and topology.sql installed? NOTICE: Function postgis_raster_scripts_installed() not found. Is raster support enabled and rtpostgis.sql installed? NOTICE: Function postgis_raster_lib_version() not found. Is raster support enabled and rtpostgis.sql installed?
Update: I've tried creating an extension to these like as follows:
CREATE EXTENSION postgis;
Then I get the following:
ERROR: PostGIS is already installed in schema 'public', uninstall first
