 I have to recreate the database '''and''' create the postgis extension
 before I can erase the link.

 The same problem arises if the database is renamed.

 There should be an option to force remove externally linked maps if the
 original doesn't exist anymore.

 I do not have this problem with raster and vector files linked via
 v./r.external and moved to another location on the disk. I can still
 remove them without any problems.
