Do you have the time to experiment with the locale settings and see if you can identify the difference between the cases where it happens and those where it doesn't? > 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 Do you have any other LC_xxx variables set? How about LANG? Is that string still a valid locale name on your updated platform? regards, tom lane
