+PostGIS setup, PostgreSQL commands, ChirpStack integration
+
+`apt install postgis`
+
+`sudo -u postgres psql` (just psql -U postgres won't work)
+
+`CREATE EXTENSION postgis;`
+
+To select from user table:
+
+`select * from public."user";` (select * from user doesn't work; shows the currently-logged in psql user instead?)
+
+`CREATE DATABASE chirpstack_integration;`
+
+`\c chirpstack_integration`
+
+`CREATE ROLE chirpstack_integration PASSWORD '6XlFKCb2ygWCt'; (need to add WITH LOGIN next time)
+
+`# GRANT ALL PRIVILEGES ON chirpstack_integration TO chirpstack_integration;` (doesn't work the way you think, see https://serverfault.com/a/198018)
+
+`ALTER DATABASE chirpstack_integration OWNER TO chirpstack_integration;`
+
+list roles:
+
+`SELECT * FROM pg_roles;`
+
+roles and users are different; roles cannot login by default and are not listed in pg_user (but all users are listed in pg_role)
+
+`ALTER ROLE chirpstack_integration WITH LOGIN;` (since I didn't do login in the first place...best to just make a user)
+
+schema for integration: https://github.com/chirpstack/chirpstack/blob/master/chirpstack/src/integration/postgresql/migrations/00000000000000_initial/up.sql
+
+q about payload decoding https://forum.chirpstack.io/t/payload-decoding-in-postgres-integration/16356
+
+the two interesting tables are event_up and event_integration
