System Configuration
---------------------
Architecture (example: Intel Pentium) : AMD Athlon
Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.17
PostgreSQL version (example: PostgreSQL-7.0): PostgreSQL-7.0.2
Compiler used (example: gcc 2.8.0) : RPM for Mandrake Linux
Please enter a FULL description of your problem:
------------------------------------------------
When inserting timestamps or interval types whose precision is one full
minute, Postgres substracts one minute from the data and add 60 seconds
(00:01:00 becomes 00:00:60). Later, when reading this data Postgres says
"Bad timestamp external representation '2000-12-14 18:25:60.00-03'" and
refuses to understand it.
I gave a look at the list of fixed bugs for 7.0.3, but it isn't listed.
(sorry, Mandrake hasn't provided upgraded packages yet, and I don't want to
mess around with the installation).
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
rwatch=> CREATE TABLE test (val1 TIMESTAMP, val2 INTERVAL);
CREATE
rwatch=> INSERT INTO test VALUES (CAST ('2000-12-14 18:25:00.00-03' AS
TIMESTAMP), CAST ('00:01:00' AS INTERVAL));
INSERT 4400170 1
rwatch=> SELECT * FROM test;
val1 | val2
---------------------------+----------
2000-12-14 18:25:60.00-03 | 00:00:60
(1 row)
(cutting and pasting the text from the select above):
rwatch=> INSERT INTO test VALUES (CAST ('2000-12-14 18:25:60.00-03' AS
TIMESTAMP));
ERROR: Bad timestamp external representation '2000-12-14 18:25:60.00-03'
If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
Sorry, I don't even know where to look. It is probably a bug in the way
CAST() treats it's arguments, when dealing with time data types.
