Implementations

impl PgMetadataLookup

pub fn lookup_type(&self, type_name: &str) -> PgTypeMetadata

Determine the type metadata for the given type_name

This function should only be used for user defined types, or types which come from an extension. This function may perform a SQL query to look up the type. For built-in types, a static OID should be preferred.
