Remove setup_postgres task and update schema RB
What does this MR do?
Since we only support Postgresql since 12.1 (https://docs.gitlab.com/ee/install/requirements.html#database) I think we can remove the setup_postgresql
rake task and move the indexes into schema.rb
.
This will mean that developers will no-longer need to ignore changes like
t.index "lower((name)::text)", name: "index_projects_on_lower_name"
in their schema.rb
file when committing.
