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?
