pip install sprockets-postgresDocumentation is available at sprockets-postgres.readthedocs.io.
The following table details the environment variable configuration options:
| Variable | Definition | Default |

POSTGRES_CONNECTION_TIMEOUT |
The maximum time in seconds to spend attempting to create a new connection. | 10 |
POSTGRES_CONNECTION_TTL |
Time-to-life in seconds for a pooled connection. | 300 |
POSTGRES_QUERY_TIMEOUT |

If POSTGRES_URL uses a scheme of postgresql+srv, a SRV DNS lookup will be performed and the lowest priority record with the highest weight will be selected for connecting to Postgres.
AWS's ECS service discovery does not follow the SRV standard, but creates SRV records. If POSTGRES_URL uses a scheme of aws+srv, a SRV DNS lookup will be performed using the correct format for ECS service discovery. The lowest priority record with the highest weight will be selected for connecting to Postgres.
