I want a method to export osm files from a Postgres database. I already have an osm2pgsql database, an apidb database, and a nominatim database in which I have imported osm files. Now I need to export osm files from a database with an osm2pgsql schema and use it with the nominatim and api-db(openstreetmap-website) database.
I know that the osm2pgsql is a tool for populating a PostGIS database that allows us to run the Mapnik rendering software, Nominatim search software, or our geospatial queries and have a different database table structure to that required by the openstreetmap-website rails app.
But, I need to create for use in future imports using osmosis and osm2pgsql tools and for backup purposes.
Can anyone help me with how to do this?
