@Gargron Ahh, weird choice on your part, but i guess its easy to ignore considering how much of a PITA it can be to do database upgrades.
Not sure what the postgres version was when i first moved over to AWS for most of my work. Wouldnt suprise me if they had a work around even on 9.x somehow.
@freemo What do you mean choice? This database started running in early 2016.
