Ran dev/generate.sh against PostgreSQL 11.5
Created by: unknwon
The primary purpose of this PR is not to merge but raise discussion about the following:
I'm using PostgreSQL 11.5, and when I intended to run ./dev/generate.sh
to generate something else for me, I notice this diff in my cmd/frontend/db/scheme.md
. I first guess is the new (11.5) psql returns more concrete column name (Modifiers vs Collation | Nullable | Default).
