Struct PostgresDialect 

Source 
pub struct PostgresDialect;
Expand description

Type-level marker for PostgreSQL.

Used by crate::row::SQLTypeToRust to provide PostgreSQL-specific type mappings. PostgreSQL uses native binary formats for dates, UUIDs, and JSON, so the corresponding feature flags (chrono, uuid, serde) must be enabled.
