Struct PostgresDialect 

Source 
pub struct PostgresDialect;
Expand description

Type-level marker for PostgreSQL.

Selects PostgreSQL type mappings (DialectTypes, SQLTypeToRust). PostgreSQL has native date/time, UUID and JSON types, so selecting them needs a matching feature (chrono, time or jiff; uuid; serde).
