+# Debian Package Build Support
+
+To setup to build for multiple Postgres releases:
+
+```sh
+sudo apt install debhelper
+
+# Add Postgres Debian repository key
+wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
+
+# Add Debian repository
+echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" |sudo tee  /etc/apt/sources.list.d/pgdg.list
+sudo apt update
+
+# Install server support
+sudo apt -y install \
+  postgresql-9.6 postgresql-client-9.6 postgresql-server-dev-9.6 \
+  postgresql-10 postgresql-client-10 postgresql-server-dev-10 \
+  postgresql-11 postgresql-client-11 postgresql-server-dev-11 \
+  postgresql-12 postgresql-client-12 postgresql-server-dev-12 \
+  postgresql-13 postgresql-client-13 postgresql-server-dev-13
+```
+
+Then edit `/etc/postgresql-common/supported_versions` to replace contents with
+
+```
+pgdg
+``` 
+
+From that point you can build all supported packages with:
+
+```sh
+make deb
+```
