+### PostgreSQL
+
+#### Get PostgreSQL logs:
+
+```sh
+docker logs deep-postgres
+```
+
+#### Connect to PostgreSQL from inside its docker container:
+
+```sh
+docker exec -it deep-postgres bash
+su postgres
+psql
+```
+
+#### Get the size of all tables in the databases and indexes:
+```sql
+SELECT
+  nspname                                               AS "schema",

+  pg_size_pretty(pg_total_relation_size(pg_class.oid))  AS "total_size",
+  pg_size_pretty(pg_relation_size(pg_class.oid))        AS "data_size",
+  pg_size_pretty(pg_indexes_size(pg_class.oid))         AS "index_size",

+JOIN 
+  pg_catalog.pg_namespace AS ns
+ON
+  pg_class.relnamespace = ns.oid
+ORDER BY 
+  pg_total_relation_size(pg_class.oid) DESC;
+```
+
+#### Get the list of active queries:
+
+```sql
+SELECT datname, pid, state, query, age(clock_timestamp(), query_start) AS age 
+FROM pg_stat_activity
+WHERE state <> 'idle' 
+    AND query NOT LIKE '% FROM pg_stat_activity %' 
+ORDER BY age;
+```
+
+#### Cancel the query
+```sql
+SELECT pg_cancel_backend(pid);
+```
