Matrix fails on Cloudron 5.6.2

[nebulon]

Apparently due to the Postgres addon collation changes, new matrix does not work anymore (existing installations will continue to work):

If you are using Matrix actively, make sure to not update your Cloudron until this is fixed! (ignore this)

@nebulon I am on 5.6.2 and Matrix is working fine for me.

Existing installations won't be affected. The addon changes only apply to new app installs.

@girish I deleted my comment as to not confuse those looking for a resolution - sorry about that.

@murgero I thought your comment was good, in fact Because @nebulon said, don't update Cloudron (but it doesn't affect existing installations). I will edit his post.
