locales and encodings Oh MY!

Hi all,

So today while I investigating some slow queries I found out that some time
ago some of our databases (due, innocently I suspect, to upgrades or
hardware migrations) are now not using C as lc_ctype. And why some 'things'
got a lot slower...

To correct this problem it seems like I am going to have to do a dump,
intidb, then restore. (or add some new indexes and eat the extra overhead).
Unless someone knows something I don't about changing ctype and collation
with some sleight of hand (if you do I am very interested)

I have listed what I think I will be doing with regards to initdb. if anyone
sees problems with the following mixture during my dump -> init-> restore I
would be most keen in hearing about it.

initdb /path/to/data/dir --lc_ctype=C --lc_collation=C
--lc_message=en_US.UTF8 --lc_monetary=en_US.UTF8 --lc_numeric=en_US.UTF8
--lc_time=en_US.UTF8 -E UTF8

Thank you,

Mark
