For installing postgresql 9.2 I followed this url : http://www.ubuntugeek.com/how-to-install-postgresql-9-2-on-ubuntu-server-using-ppa.html
But at the end of installation output is like :
Setting up postgresql-common (140~precise) ...
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
Adding user postgres to group ssl-cert
Building PostgreSQL dictionaries from installed myspell/hunspell packages...
* No PostgreSQL clusters exist; see "man pg_createcluster"
Setting up postgresql-9.2 (9.2.4-0ppa1~precise) ...
Error: The locale requested by the environment is invalid.
Error: could not create default cluster. Please create it manually with
pg_createcluster 9.2 main --start
or a similar command (see 'man pg_createcluster').
update-alternatives: using /usr/share/postgresql/9.2/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode.
* No PostgreSQL clusters exist; see "man pg_createcluster"
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place
And when I tried to start postgresql, it gives following error :
sudo /etc/init.d/postgresql start
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_MESSAGES = "en_IN.UTF-8",
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
* No PostgreSQL clusters exist; see "man pg_createcluster"
How can I fix this problem ?
