Move/update cscope_gens

Hopefully I can make this work nicely with Scala.
Create .psqlrc file

I should have done this ages ago.

psql is one of the few commands that gets a dedicated screen/tmux/i3
window dedicated to it and somehow I never deemed it worthy of investing
for some rc file action. I've only scratched the surface, but I've
already got more pleasing fonts and most importantly - automatic
extended display whenever I'm viewing more columns than 1 row of the
screen can handle.
