## Installation

### Run with docker

```bash
docker run -p 5432:5432 -e POSTGRES_PASSWORD=postgres quay.io/tembo/pglater-pg:latest
```

If you'd like to build from source, you can follow the instructions in [CONTRIBUTING.md](https://github.com/tembo-io/pg_later/blob/main/CONTRIBUTING.md).

### Using the extension

Initialize the extension's backend:

```sql
CREATE EXTENSION pg_later CASCADE;

SELECT pglater.init();
```

Execute a SQL query now:

```sql
select pglater.exec(
'select * from pg_available_extensions order by name limit 2'
) as job_id;
```

```text
job_id
--------
1
(1 row)
```

Come back at some later time, and retrieve the results by providing the job id:

```sql
select pglater.fetch_results(1);
```

```text
pg_later_results
--------------------
{
"query": "select * from pg_available_extensions order by name limit 2",
"job_id": 1,
"result": [
