Обсуждение: running initdb on running database

Admins,

I'm reading this post:

http://archives.postgresql.org/pgsql-novice/2005-04/msg00221.php

Is it possible and safe to run initdb again on a running database to
change encoding from SQL_ASCII to UTF8?

Will it affect new databases only or existing databases as well?



Thanks.

Pretty much guaranteed to be unsafe. It's also not possible unless you
hack initdb.

Thanks.

I guess then the next upgrade may be the best opportunity to change the
encoding.
