Of course the internal representation of timestamp with time zone data type is not affected by the time zone setting. But why other form of to_timestamp is labeled as stable? If your theory is correct, then other form of to_timestamp shouldn't be labeled immutable as well? Best reagards, -- Tatsuo Ishii SRA OSS, Inc.
