Support postgres 12 and dot notation

[ispyhumanfly]

Top of my list for scribe is to make it work with postgres 12 and the new dot notation it has for querying into data stored as json. That will fix soooo many queries we have going on right now that have to query the entirety of a table just to find things. Like right now in order to determine all the projects a user is in the only way to do it is to query for the entire project table and then use a javascript filter on it…. It’s just getting slower and slower and slower as the db grows
