Description: sorting order
Details:

Hi

I have 8.3.5 installed. The sorting order in potsgres would be determined by
lc_collate.

I am not passing the value of lc_collate during initdb. initdb takes the
value from locale of the system.

I see that with locale C/en_us and en_US.UTF-8, I get different sort for
same data in particular column of the table.

I would like to know if there is anyway we can get the same sorting order
irreespective of lc_collate value when doing the select query.

If yes, please let me know the select query.

If not, I would like to confirm if lc_collate value is used only for sorting
purpose. If so can I hardcode lc_collate value during initdb? does it affect
anyway the localization support of database.

Thanks in advance
Savita
