 This will trigger the [Release EQL](https://github.com/cipherstash/encrypt-query-language/actions/workflows/release-eql.yml) workflow, which will build and attach artifacts to [the release](https://github.com/cipherstash/encrypt-query-language/releases/).

+We publish a Trusted Language Extension for PostgreSQL for use on [dbdev](https://database.dev/).
+You can find the extension on [dbdev's extension catalog](https://database.dev/cipherstash/eql).
+
+#### Publishing to dbdev
+
+**DISCLAIMER:** At the moment, we are manually publishing the extension to dbdev and the versions might not be in sync with the releases on GitHub until we automate this process.
+
+Steps to publish
+
+> [!NOTE]
+> Make sure you have the [dbdev CLI](https://supabase.github.io/dbdev/cli/) installed and logged in using the `dbdev shared token` in 1Password.
+
+1. Run `mise run build` to build the extension which will create the following file in the `dbdev` directory. (Note: this release artifact is built from the Supabase release artifact).
+2. After the build is complete, you will have a file in the `dbdev` directory called `eql--0.0.0.sql`.
+3. Update the file name from `eql--0.0.0.sql` replacing `0.0.0` with the version number of the release.
+4. Also update the `eql.control` file with the new version number.
+5. Run `dbdev publish` to publish the extension to dbdev.
