My system's locale is en_US.UTF-8. Because of that, the postgreSQL installation uses this locale by default for the cluster during installation.
Creating new cluster 9.3/main ...
config /etc/postgresql/9.3/main
data /var/lib/postgresql/9.3/main
locale en_US.UTF-8
port 5432
But I want my postgreSQL server to install with locale pt_BR.UTF-8. Is it possible?
