Struct PostgresService 

pub struct PostgresService;

Cordis Service for postgres availability — runtime check replaces #[cfg(feature = "postgres")] in handlers.

check() returns cfg!(feature = "postgres") so both cargo check --no-default-features and cargo check --features postgres compile; handlers branch via PostgresService::check() or cfg!.
