Hi Herve,
See you've released Database Plug-in 4.9.5, I'm using 4.9.3 now which is OK, however, when installing 4.9.5 I got below "invalid distance code" error.

Thanks Phil, https://github.com/archi-contribs/database-plugin/issues/152 (https://github.com/archi-contribs/database-plugin/issues/152) issue #152 submitted.
I did try it myself and it was OK. The error suggests an unzipping issue or corrupt archive file, so maybe download it and try again?
