Sarah Hoffmann 9cf85f90fb Simplify parsing of postgres and postgis versions
Switch to functions server_version_num and postgis_lib_version
which both only return the version string, so that no elaborate
string parsing is necessary anymore. The version string could
become especially cumbersome in pre-release versions.
