mysql privileges

[jonium]

Hello,
a user in shared hosting on a dedicated ask me if is possible to give the following permission to his mysql user:
UPDATE user SET File_priv = 'Y' WHERE User = 'his_mysql_user';
FLUSH PRIVILEGES;
in order to write csv files in his webspace.
Do you think it is safe?
