What to use for GUIDS ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

We are using GUIDS as primary keys. At the moment we’re using a varchar 32. We’d like to use varchar 16 but had some problems with the generated chars; we were using UNICODE locale (we’re now using WIN1251). Should we use bytea, retry varchar 16 (with the new local), or some other column type ?? What is going to give us the best performance (with 8.1) ?

 

Thank You
