tpl/pureftpd_mysql.conf.master uses wrong value for datetime range
Queries in pureftp config include expires="0000-00-00 00:00:00"
. The value is wrong as it is outside of supported range - see https://dev.mysql.com/doc/refman/8.0/en/datetime.html
The supported range is '1000-01-01' to '9999-12-31'.
Maybe it's new behavior of MySQL 8. Anyway removing these parts from queries made my system work correctly.
