fn pg_oid_alias_type(column: &ColumnSchema) -> Option<Type>Expand description
Maps datafusion-pg-catalog OID-alias metadata to PostgreSQL wire types.
The catalog exposes static catalog aliases as Utf8 and dynamic aliases
as Int32, so this must run before the ordinary INT4/VARCHAR fallbacks.
The catalog crate only exposes named constants for the aliases it uses in
dynamic catalog tables; keep the remaining aliases here for compatibility
with its public OID_ALIAS_TYPE_NAMES contract. See
