How _completely_ remove/deinstall databases/mysql57-server

[Aryeh Friedman]

I have completely corrupted my mysql installation and doing a reinstall
from ports does not fix it.... How do I completely remove
database/mysql57-server from my machine (including _all_
database/config/etc. files [these are what make deinstall _does not_
remove])
