Hi Medi,
I have only limited experience in this area, but it sounds like you
sending your numbers as strings? In your example:
>create table t1 { name text, cost decimal };
insert into t1 (name, cost) values ('name1', '1');
I can't think of how else you're sending numeric values as UTF8? I know
that Pg will accept numbers as strings and convert internally (that has
worked for me in some object relational environments where I don't
choose to cope with data types), but I think it would be better if you
simply didn't send your numeric data in quotations, whether as UTF8 or
ASCII. If you don't have control over this layer (that quotes your
values), then I'd say converting to ASCII would solve the problem. But
better to convert to numeric and not ship quoted strings at all.
I may be totally off-base and missing something fundamental and I'm
very open to correction (by anyone), but that's what I can see here.
Best regards,
Steve
