Re: [GENERAL] int8-datatype: possible bug

Hello José Soares,

thank you. I tried your testcase and all input was changed in the magical 
value. The 'NOTICE' disappeared when I quoted the value, but the result 
was all the same.

edahrecepten=> create table test(i8 int8);
CREATE
edahrecepten=> insert into test values(19980528112607 );
NOTICE:  Integer input '19980528112607' is out of range; promoted to float
INSERT 147055 1
edahrecepten=> select * from test;
                 i8
-------------------
9223091440198811892
(1 row)

edahrecepten=> insert into test values('19980528112607' );
INSERT 147056 1
edahrecepten=> select * from test;
                 i8
-------------------
9223091440198811892
9223091440198811892
(2 rows)

edahrecepten=> insert into test values('19980528112607'::int8);
INSERT 147057 1
edahrecepten=> select * from test;
                 i8
-------------------
9223091440198811892
9223091440198811892
9223091440198811892
(3 rows)

edahrecepten=> select version();
version                                             
----------------------------------------------------
PostgreSQL 6.4.2 on mips-sgi-irix6.2, compiled by cc
(1 row)

So for the time being I use float8...

Jelle.
