Hello.
 
I am new to postgres. I installed 7.3 on a windowsXP machine (I used PgSQL731wina1.exe).
I create a database with Greek encoding iso-8859-7.
 
The sql queries
    SELECT upper(aField) FROM aDatabase 
    or
    SELECT lower(aField) FROM aDatabase 
 
work ok with US characters but for the Greek characters no conversion is made
 
can anyone help me with this problem
 
Thank you,
    Panagiotis
