Re: Issue on Varchar Ordering

Yeah, I think there's a problem on Linux locales.

Using the C locale, it works as expected:

rodrigo@asgard:~$ export LC_ALL=C && cat test.txt | sort
GABRIEL ALCIDES KLIM PERONDI
GABRIEL ALEXANDRE DA SILVA MANICA
GABRIELA HELEDA DE SOUZA
GABRIELA JACOBY NOS
GABRIELA LETICIA BATISTA NUNES

But when using Brazilian Portuguese, it gives:

rodrigo@asgard:~$ export LC_ALL=pt_BR && cat test.txt | sort
GABRIELA HELEDA DE SOUZA
GABRIELA JACOBY NOS
GABRIEL ALCIDES KLIM PERONDI
GABRIELA LETICIA BATISTA NUNES
GABRIEL ALEXANDRE DA SILVA MANICA

rodrigo@asgard:~$ export LC_ALL=pt_BR.UTF-8 && cat test.txt | sort
GABRIELA HELEDA DE SOUZA
GABRIELA JACOBY NOS
GABRIEL ALCIDES KLIM PERONDI
GABRIELA LETICIA BATISTA NUNES
GABRIEL ALEXANDRE DA SILVA MANICA

rodrigo@asgard:~$ export LC_ALL=pt_BR.ISO-8859-1 && cat test.txt | sort
GABRIELA HELEDA DE SOUZA
GABRIELA JACOBY NOS
GABRIEL ALCIDES KLIM PERONDI
GABRIELA LETICIA BATISTA NUNES
GABRIEL ALEXANDRE DA SILVA MANICA

The fact is that I can't raise PostgreSQL with C encoding, as special characters are used on most tables.

Did anyone ever had the same problem on Linux?
