Ah yes, this is likely why. pg_config says CONFIGURE = ... '--disable-integer-datetimes' ... But I'm having trouble seeing for sure whether there are submicrosecond parts of these timestamps. I just see a bunch of '00:00:00' values with your query: test=# SELECT ts - '1999-12-31 19:00:00-05'::timestamptz FROM timestamps_test LIMIT 5; ?column? ---------- 00:00:00 00:00:00 00:00:00 00:00:00 00:00:00 (5 rows) And SELECT EXTRACT(microseconds FROM ts) FROM timestamps_test also just gives me zeroes. Is there a way for me to see for sure?
