Dear all,
As a hobby project, I am toying around with a database containing
about 5 million chess games. On average, these games have about 80
positions (~ 40 moves by both black and white), which means there are
about 400 million chess positions in there.
I have written code to extract these pos
Hi,
I think it would be very good, if postgresql reports which column is too small:
Value to long for type character varying(1024) (message translated from
german to english)
Is there a reason not to report the column name?
How can you report feature request?

Hi,
I'm looking for materials about query optimization in PostgreSQL. I read
documentation but it doesnt contain much information. Can you recommend a good
book or website when i could learn something about this?
thanks in advance for your help

Hi All,
I am trying to setup PostgreSQL 9.1.3 for OS authentication when connecting
through jdbc driver. Correct me if I am wrong, but:
- I cannot use SSPI, because current jdbc driver does not support it
- I cannot use GSSAPI, because Windows binary is not built with this support
and cannot afford
