Problem statement
Add support for Django 5.1 PostgreSQL connection pools to env.db_url
From the Django 5.1 release notes:
> Django 5.1 also introduces [connection pool](https://docs.djangoproject.com/en/5.1/ref/databases/#postgresql-pool) support for PostgreSQL. As the time to establish a new connection can be relatively long, keeping connections open can reduce latency.
>
> To use a connection pool with [psycopg](https://www.psycopg.org/), you can set the "pool" option inside [OPTIONS](https://docs.djangoproject.com/en/5.1/ref/settings/#std-setting-OPTIONS) to be a dict to be passed to [ConnectionPool](https://www.psycopg.org/psycopg3/docs/api/pool.html#psycopg_pool.ConnectionPool), or to True to use the ConnectionPool defaults:
```
DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql",
# ...
"OPTIONS": {
"pool": {
"min_size": 2,
"max_size": 4,
"timeout": 10,
}
},
},
}
```
https://docs.djangoproject.com/en/5.1/releases/5.1/#postgresql-connection-pools
The format does not lend itself well to be passed as query params in the DATABASE_URL.
Perhaps they can be passed in a new `extra_options` argument?
```python
env.db_url(extra_options={
"pool": {"min_size": 2, "max_size": 4, "timeout": 10}
})
```
