- `sslmode`, integer. Used for drivers `mysql` and `postgresql`. 0 disable TLS connections, 1 require TLS, 2 set TLS mode to `verify-ca` for driver `postgresql` and `skip-verify` for driver `mysql`, 3 set TLS mode to `verify-full` for driver `postgresql` and `preferred` for driver `mysql`
- `root_cert`, string. Path to the root certificate authority used to verify that the server certificate was signed by a trusted CA
- `disable_sni`, boolean. Allows to opt out Server Name Indication (SNI) for TLS connections. Default: `false`
- `target_session_attrs`, string. This is a `postgresql` and `cockroachdb` specific option. It determines whether the session must have certain properties to be acceptable. It's typically used in combination with multiple host names to select the first acceptable alternative among several hosts. Supported values: `any`, `read-write`, `read-only`, `primary`, `standby`, `prefer-standby`. If empty, `any` is assumed.

It's typically used in combination with multiple host names to select the first acceptable alternative among several hosts. Supported values: `any`, `read-write`, `read-only`, `primary`, `standby`, `prefer-standby`. If empty, `any` is assumed. If you explicitly set `any` the connections will be randomly distributed among the specified hosts
- `client_cert`, string. Path to the client certificate for two-way TLS authentication
- `client_key`,string. Path to the client key for two-way TLS authentication
- `connection_string`, string. Provide a custom database connection string. If not empty, this connection string will be used instead of building one using the previous parameters. Leave empty for drivers `bolt` and `memory`
