As PostgreSQL stores timestamps with a fractional part, does it mean that WHERE f BETWEEN '2012-04-23 00:00:00' AND '2012'04-23 23:59:59' might miss records with values of f equal to 23:59:59.1234 or so? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
