4. We will create a different database only for this recipe, as we will use this
OSM database in other chapters. For this purpose, create a new database
named
rome
and assign privileges to your user:
postgres=# CREATE DATABASE rome OWNER me;
postgres=# \connect rome;
rome=# create extension postgis;
5. You will not create a different schema in this new database, though, as the
osm2pgsql
commandcanonlyimportOSMdatainthepublicschemaatthe
time of writing.
