Prerequisites

The postgis package appropriate for the version of postgres server you have installed (in my case, 11)

Ubuntu

• sudo apt install shp2pgsql osm2pgsql
• sudo apt install postgresql-11 postgresql-11-postgis-3
• The postgresql server started/running/configured and databases gis and osm created

Running

• Run the following SQL inside the gis database to enable the PostGIS and hstore extensions: CREATE EXTENSION postgis; CREATE EXTENSION hstore;
• Unzip the original_data and open a shell in that folder.
• Then, run from your shell: shp2pgsql -s 3735:4326 -g geom -I Parcels__Public_.shp | psql -d gis -U postgres -W
• shp2pgsql -s 3735:4326 -g geom -I Sonoma_County_Building_Outlines.shp | psql -d gis -U postgres -W
• osm2pgsql -d gis -c --prefix son --slim --extra-attributes --hstore --latlong sonoma-orig-buildings-20201219.osm -U postgres -W

Now all the data is in Postgres. For processing and conflation, read through and execute conflation.sql as per your comfort level.
