+# dockerized postgres
+
+You can use dockerized postgres to query your database, and manage backups, without locally installing postgres.
+
+The commands work as usual, except:
+
+- Use `host.docker.internal` instead of `localhost`.
+- You can only access files in the current working directory (e.g. when dumping).
+
+## psql
+
+```shell
+dockerized psql --host "host.docker.internal" --username <username>
+```
+
+## pg_dumpall
+
+```shell
+  dockerized pg_dumpall \
+    --host "host.docker.internal" \
+    --file "backup.sql" \
+    --username root \
+    --no-password \
+    --quote-all-identifiers \
+    --verbose
+```
