Nominatim/sql/functions.sql
Sarah Hoffmann b0e6fb73c6 generally remove all country and state places from address 
Gets rid of the hard-coded expection for place nodes and sets
the address rank generally via the address level config instead.
That means only administrative boundaries are now used at that
level in addresses.
