But it's not that simple.  If one could flip a switch and change a 
postgresql installation from one locale to another, then hey, no big deal.  
If indexes on text worked right in other locales it would be no big deal.  

If you don't choose locale=C with doing initdb then you 
have to backup the whole database, reinitdb, and restore it in order to 
switch to it.

If the postgresql engine could use indexes well in all 
locales then it would be reasonable to pick up the environmental locale.  
As long as locale C is the only one that can use indexes on text, it's not 
reasonable to use the locale of the environment without knowing what the 
user really wants to do with the database.

Especially since most of the folks I know who download it are going to 
prefer a locale of C to en_US or whatnot, since they'll likely want fast 
indexed access on text types.

I would at least suggest that certain locales default to be coerced to C 
if the user doesn't pick one.
