Quickstart

Set the following ENV VARS:

PG_META_HOST="0.0.0.0"
PG_META_PORT=8080
PG_META_DB_HOST="postgres"
PG_META_DB_NAME="postgres"
PG_META_DB_USER="postgres"
PG_META_DB_PORT=5432
PG_META_DB_PASSWORD="postgres"

Then run any of the binaries in the releases.

FAQs

Why?

This serves as a light-weight connection pooler. It also normalises the Postgres system catalog into a more readable format. While there is a lot of re-inventing right now, this server will eventually provide helpers (such as type generators). The server is multi-tenant, so it can support multiple Postgres databases from a single server.

What security does this use?

None. Please don't use this as a standalone server. This should be used behind a proxy in a trusted environment, on your local machine, or using this internally with no access to the outside world.

Developers

To start developing, run npm run dev. It will set up the database with Docker for you. The server will restart on file change.

If you are fixing a bug, you should create a new test case. To test your changes, add the -u flag to vitest on the test:run script, run npm run test, and then review the git diff of the snapshots. Depending on your change, you may see id fields being changed - this is expected and you are free to commit it, as long as it passes the CI. Don't forget to remove the -u flag when committing.

To make changes to the type generation, run npm run gen:types:<lang> while you have npm run dev running, where <lang> is one of:

  • typescript
  • go
  • swift (beta)

To use your own database connection string instead of the provided test database, run: PG_META_DB_URL=postgresql://postgres:postgres@localhost:5432/postgres npm run gen:types:<lang>
