I created Postgres 8 database in Windows XP using CREATE DATABASE mydb ENCODING='UNICODE'; and upsized data to it. The query SELECT name FROM customer ORDER BY UPPER(name); returns error ERROR: invalid multibyte character for locale HINT: The server's LC_CTYPE locale is probably incompatible with the database encoding. How I can get customer list in case-insensitive alphabetical order ? The query SELECT name FROM customer runs OK ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
