Hi,
consider the following:
select quote_literal(blank_hms) as "quote_literal(blank_hms)", blank_hms::timestamp as
"blank_hms::timestamp" from (select unnest(array['2011-07-22 :', '2011-07-22 : ', '2011-07-22 : :
']::text[]) as blank_hms) a; select version();
quote_literal(blank_hms) | blank_hms::timestamp
--------------------------+----------------------
'2011-07-22 :' | 2011-07-22 00:00:00
'2011-07-22 : ' | 2011-07-22 00:00:00
'2011-07-22 : : ' | 2011-07-22 00:00:00
(3 rows)
Time: 0.264 ms
version
------------------------------------------------------------------------------------------------------------------
PostgreSQL 9.0.3 on x86_64-manual_install-freebsd8.x, compiled by GCC cc (GCC) 4.2.1 20070719
[FreeBSD], 64-bit
(1 row)
The result is what might be expected by the common sense means.
Howewer, the input format of the example datetime strings is definitely wrong as far as I guess.
Some other datetime parsers reject it, the Perl DateTime::Format::Pg is an example.
Is this case a subject of eventual corrections in the future versions of postgres and it would start
emit errors then?
Thanks
Irek.
