looks good to me... is this ready to be merged?

[ImreSamu]

is this ready to be merged?

yes ..
it is working for me .. ( and I have tested with my local project )

ps:

• probably other postgis users would like to test the new 12-master / 13-master image ..
  * imho: it would be a good idea to make a small anouncement about the testing possibility in the postgis-users mail list :)
