Oh. That's very interesting. Thank you, David. I will chase up with the
developers tomorrow to confirm with them the version of the postgres

I'm no coder, it didn't occur to me to actually check with the source.

Whatever you've got planned, forget it. I'm the Doctor.
I'm 904 years old. I'm from the planet Gallifrey in the
constellation of Kasterborous. I am The Oncoming Storm,
the Bringer of Darkness and you are ... basically just a
rabbit, aren't you? OK, carry on, just a general ...
warning.
I'm guessing this is now resolved ?
