While the syntax may vary slightly, there are equivalent commands for most things in spatialite and there's a great intro cookbook http://www.gaia-gis.it/spatialite-2.4.0-4/spatialite-cookbook/index.html You should be able to apply the same knowledge to postgis.
Also lookup bostongis postgis, lots of great tips there.
