### NixOS - usage:
|
|
==================
|
|
|
|
services.postgresql.extraPlugins = [ (pkgs.postgis.override { postgresql = pkgs.postgresql95; }).v_2_2_1 ];
|
|
|
|
|
|
### important Postgis implementation details:
|
|
=============================================
|
|
|
|
Postgis provides a shared library implementing many operations. They are
|
|
exposed to the Postgres SQL interpreter by special SQL queries eg:
|
|
|
|
CREATE FUNCTION [...]
|
|
AS '[..]liblwgeom', 'lwhistogram2d_in' LANGUAGE 'C' IMMUTABLE STRICT; -- WITH (isstrict);
|
|
|
|
where liblwgeom is the shared library.
|
|
Postgis < 1.5 used absolute paths, in NixOS $libdir is always used.
|
|
|
|
Thus if you want to use postgresql dumps which were created by non NixOS
|
|
systems you have to adopt the library path.
|
|
|
|
|
|
### TODO:
|
|
=========
|
|
the bin commands to have gtk gui:
