This in a pretty huge change. At a high level we're adding the concept
of a 'contact' which is a person or organization that has zero or more
contact methods (email, phone). This ended up cascading a number of
changes, including critically to the publicreprt schema. In the end it
seemed safer to get to the point where I'm confident we aren't using any
of the old fields for storing reporter information (though I haven't
deleted the columns yet) so I removed the code for defining those
columns.
At this point I think it's not possible for me to regenerate the bob
schema due to the interdependencies between my various schemas, so the
migration is well-and-truly happening.
This is a huge change. I was getting really sick of the split between
nuisance/water tables when more than half of the data they store is
common. I finally bit off the big work of switching it all.
This creates a single unified table, publicreport.report and copies the
existing report data into it. It also ports existing data from the
original tables into the new table.
Along with all of this I also overhauled the system for handling
asynchronous work to use a LISTEN/NOTIFY connection from the database
and a single cache table to avoid ever losing work.
