Thank you Alexandre for this quick answer.
As you suggested, I'm moving this discussion in the TinyOWS mailing list.
I'll see what this workaround is and try to make the INSERT work.
By the way, TinyOWS has been fairly simple to configure and has answered our
needs. We're pretty satisfied thus far.
