n_sign_posn and p_sign_posn are considered as string by trytond.convert
while testing 5.0 to 5.2 migration, I saw some unsynchronized ir.lang data. After resynchronized them, trytond.convert process (called by trytond-admin) complains:
"Field p_sign_posn of 9@ir.lang not updated (id: lang_fr), because it has changed since the last update"
after discussion on irc (https://www.tryton.org/~irclog/2019-05-24.log.html#t09:05-2), it has been noted that the field is an integer whereas the value is defined as char in XML.
By itself the problem is harmless, but it adds noise in trytond.convert process.
