Import new tags for noise, green and water feature
- A PostgreSQL and a osm2pgsql installation is needed
see https://www.postgresql.org/
and https://osm2pgsql.org/
- and a jdbc driver
see https://jdbc.postgresql.org/download/
- prepare database
```
# postgres createdb --encoding=UTF8 -U postgres osm
# postgres psql -U postgres osm --command='CREATE EXTENSION postgis;'
```
- import to database and create
```
# osm2pgsql -c -s -d osm -U postgres -W -H localhost -P 5432 -O flex -S brouter_cfg.lua /path/to/file.pbf
```
- generate new tags inside the database (use `<` if `-f` does not work)
```
# postgres psql -d osm -U postgres -f brouter.sql
```
- prepare generation of pbf
- lookups.dat has to contain the new tags from the database
- script needs a jdbc in the classpath (on UNIX and Linux use a colon `:` as delimiter)
`... -cp ../postgresql-42.6.0.jar;../brouter_fc.jar ...`
- script needs a call with jdbc parameter
define the database parameter
`JDBC="jdbc:postgresql://localhost/osm?user=postgres&password=xyz&ssl=false"`
- export the tags from database to filesystem
`java -Xmx6144M -Xms6144M -Xms6144M -cp %CLASSPATH% btools.mapcreator.DatabasePseudoTagProvider $(JDBC) db_tags.csv.gz`
- call it with OsmFastCutter as last parameter (behind pbf file)
`... btools.mapcreator.OsmFastCutter ... ../planet-new.osm.pbf db_tags.csv.gz`
