Migrate from Render to Supabase
Migrate your Render Postgres database to Supabase.

Render is a popular Web Hosting service in the online services category that also has a managed Postgres service. Render has a great developer experience, allowing users to deploy straight from GitHub or GitLab. This is the core of their product and they do it really well. However, when it comes to Postgres databases, it may not be the best option.

Supabase is one of the best free alternative to Render Postgres. Supabase provide all the backend features developers need to build a product: a Postgres database, authentication, instant APIs, edge functions, realtime subscriptions, and storage. Postgres is the core of Supabase—for example, you can use row-level security and there are more than 40 Postgres extensions available.

This guide demonstrates how to migrate from Render to Supabase to get the most out of Postgres while gaining access to all the features you need to build a project.

Retrieve your Render database credentials [#retrieve-render-credentials]

  1. Log in to your Render account and select the project you want to migrate.
  2. Click Dashboard in the menu and click in your Postgres database.
  3. Scroll down in the Info tab.
  4. Click on PSQL Command and edit it adding the content after PSQL_COMMAND=.

Copying PSQL command from Render dashboard Example:

%env PSQL_COMMAND=PGPASSWORD=RgaMDfTS_password_FTPa7 psql -h dpg-a_server_in.oregon-postgres.render.com -U my_db_pxl0_user my_db_pxl0

Retrieve your Supabase connection string [#retrieve-supabase-connection-string]

  1. If you're new to Supabase, create a project. Make a note of your password, you will need this later. If you forget it, you can reset it here.

  2. Go to the Database settings for your project in the Supabase Dashboard.

  3. Under Connection string, make sure Use connection pooling is enabled. Copy the URI and replace the password placeholder with your database password.

Migrate the database

The fastest way to migrate your database is with the Supabase migration tool on Google Colab. Alternatively, you can use the pg_dump and psql command line tools, which are included in a full PostgreSQL installation.

  1. Set the environment variables (PSQL_COMMAND, SUPABASE_HOST, SUPABASE_PASSWORD) in the Colab notebook.
  2. Run the first two steps in the notebook in order. The first sets the variables and the second installs PSQL and the migration script.
  3. Run the third step to start the migration. This will take a few minutes.

Export your Render database to a file in console [#export-render-database]

Use pg_dump with your Render credentials to export your Render database to a file (e.g., render_dump.sql).

pg_dump --clean --if-exists --quote-all-identifiers \
 -h $RENDER_HOST -U $RENDER_USER -d $RENDER_DATABASE \
 --no-owner --no-privileges > render_dump.sql

Import the database to your Supabase project [#import-database-to-supabase]

Use psql to import the Render database file to your Supabase project.

psql -d "$YOUR_CONNECTION_STRING" -f render_dump.sql

Additional options

  • To only migrate a single database schema, add the --schema=PATTERN parameter to your pg_dump command.
  • To exclude a schema: --exclude-schema=PATTERN.
  • To only migrate a single table: --table=PATTERN.
  • To exclude a table: --exclude-table=PATTERN.

Run pg_dump --help for a full list of options.
