Hi Marc!
* libraries/mysql_wrappers.lib.php3: bug 795443: wrong results coming
from mysql_list_fields, so modify PMA_mysql_list_fields to use
SELECT * FROM db.table LIMIT 1
(Thanks to Peter Beckman (ooglek))
I haven't looked into this, but your ChangeLog-entry rang a bell: Couldn' we instead use 'SHOW FIELDS FROM'...?
I think that selecting the first row from a table could lead to performance issues. Like when you have a table having about 1MB binary data in a blog in the row, the database would have to fetch all data if understand correctly.
