7.0.3 -> 7.1.2; pg_setlocale error

Hi,

I am trying to migrate from 7.0.3 to 7.1.2. I just got the
rpms from rawhide of redhat.

While loading the 7.0.3 dump_file to 7.1.2, I got these errors...

ERROR: stat failed on file '/usr/lib/pgsql/plpgsql.so': No such file or
directory
ERROR: PL handler function plpgsql_call_handler() doesn't exist
You are now connected as new user postgres.
NOTICE: copy: line 1, pg_setlocale(): 'LC_COLLATE=Ȁ' cannot be honored.
NOTICE: copy: line 1, pg_setlocale(): 'LC_CTYPE=°T0(at)X' cannot be honored.
NOTICE: copy: line 1, pg_setlocale(): 'LC_MONETARY=X˜' cannot be honored.

and these showed in /var/log/postgresql

I fixed the error on plpgsql.so by 'perl -pi.bak -e
's|/usr/lib/pgsql/plpgsql.so|/usr/lib/plpgsql.so|g' dump_file'
but I'm still confuse with notice on pg_setlocale.

Will it do harm to the data?

Thanks.
