Setting of locales at runtime ?

Hi,

I have question about postgres: it is possible (or planned) to change
locales (and sorting) at runtime ? For example, I will have 2 tables, in 2
different languages. I want following:

set locale cs;
select * from table1 order by 1; // this will sort by first column
// and use czech locale

set locale es;
select * from table2 order by 2; // this will sort using spanish locale

thanks,

David
