LibreSource does support only Postgresql and when the database is on a remote computer, a shared network directory should be done between the database computer and the libresource computer for the file storing in the DB.
Regarding your locking error, I have no idea...
Thank you Sebastien Jourdain
But the sequoia database is joined two postgresql database .
It's same sql language
I thought that libresource just need a change of the driver.
May be it will be work.
This does not support?
