Problems with pgsql 8.0.4 & freebsd 6: partially solved

I have been using a postgresql 8.0.4 server under freebsd 5.4 like a
charm for a long time .
Yesterday, I upgraded freebsd from 5.4 to 6 via
the CD (the iso was downloaded from ftp.freebsd.org).

Restating
postgresql it happened:

# /usr/local/etc/rc.d/010.pgsql.sh start
--:
not found
FATAL: XX000: failed to initialize lc_messages to ""
LOCATION: InitializeGUCOptions, guc.c:3699
#

And the server was down

After many attempts I discovered that the problem was connected to the
"setenv LC_ALL it_IT.ISO_8859-1" I had introduced in /usr/local/pgsql/.
cshrc
which corrupted something in the system and, even removing the
line, 010.pgsql.sh went on failing to start the server

Having
pg_dumped the data before the upgrading to 6, I have solved the problem
by
1) eliminating the /usr/local/pgsql/data directory (BY THE WAY,
remember to backup the pgsql *.conf files somewhere!!);
2) deinstalling
the postgresql 8.0.4 server by means of "make deinstall";
3) removing
the pgsql user;
4) reinstalling the postgresql 8.0.4 server;
5) copying
the *.conf files under the data directory
6) pg_restoring the data

Now, of course I have left unmodified the .cshrc file (take notice that
any attempt of modyfying the locale corrupts the postgresql server and
you should start with a new reinstallation! I failed both adding a line
"setenv LC_ALL it_IT.ISO_8859-1" and "setenv LC_ALL it_IT.ISO8859-1")

Now it all works even though an inoffensive warning comes up

#
/usr/local/etc/rc.d/010.pgsql.sh start
--: not found

Is there anything
else I could do?

Ciao
