Struct DbConfig 

pub struct DbConfig {

    pub deploy: BackendDeployConfig,
    pub host: String,
    pub port: u16,
    pub database: String,
    pub role: String,
    pub password: String,
    pub ssl_mode: String,
    pub pooler_dsn: String,
    pub direct_dsn: String,
    pub max_open_conns: i32,
    pub max_idle_conns: i32,
    pub conn_max_lifetime_secs: u64,
    pub conn_max_idle_secs: u64,
    pub min_connections: i32,
    pub acquire_timeout_secs: u64,
}

Configuration for a single PostgreSQL connection role (primary / backup / signal).

PostgreSQL is the only backend that hosts the migration ledger tables. The Go UDB service resolves DSN strings from these fields. Mirrors the legacy Go service DBConfig shape.

Fields

deploy: BackendDeployConfig

Deployment mode: SelfHosted (Docker / on-premise) or Cloud (Neon, Supabase, RDS, Aiven, etc.). Drives TLS defaults and pooler DSN format.

host: String

PostgreSQL host (e.g. "localhost", Neon project hostname).

port: u16

TCP port, defaults to 5432.

database: String

Database name.

role: String

Role / user name.

password: String

Password (resolved from env; never logged or serialised in cleartext).

ssl_mode: String

SSL mode: "require", "disable", "prefer". When empty, derived from deploy.mode: Cloud → "require", SelfHosted → "prefer".

pooler_dsn: String

Pooler DSN (PgBouncer / Neon pooled endpoint) for application traffic.

direct_dsn: String

Direct DSN (non-pooled) for migrations and DDL.

max_open_conns: i32

Maximum open connections in the pooler. Zero uses DEFAULT_DB_MAX_OPEN_CONNS; backend instances may override it.

max_idle_conns: i32

Maximum idle connections in the pooler.

conn_max_lifetime_secs: u64

Connection max lifetime in seconds. Zero uses the system-wide default.

conn_max_idle_secs: u64

Connection max idle time in seconds. Zero uses the system-wide default.

min_connections: i32

Minimum connections in the pool. Default is the system-wide DEFAULT_DB_MIN_CONNECTIONS; per-instance values win.

acquire_timeout_secs: u64

Connection acquire timeout in seconds. Default is the system-wide DEFAULT_DB_ACQUIRE_TIMEOUT_SECS; per-instance values win.

Implementations

impl DbConfig

pub fn is_configured(&self) -> bool

Returns true when the minimum required fields (host, database, role) are set.

pub fn effective_ssl_mode(&self) -> &str

Returns the effective SSL mode, falling back to a deploy-mode default when ssl_mode is empty: Cloud → "require", SelfHosted → "prefer".

pub fn masked_log(&self) -> String

Returns a log-safe masked representation (host + role; password redacted).
