Note that in most cases you can't just whack the encoding around without
paying attention to locale. I believe the only locale that really works
with multiple encodings is "C" --- all the other ones assume a
particular encoding. You'll get very odd and unpleasant results from
text sorting and functions like upper/lower if you have the database
locale and encoding set incompatibly.
Unfortunately we don't currently support changing locale on the fly ---
so you can only set it at initdb time. So the -E switch to createdb
is a bit dangerous.
This stuff is covered in the docs at
