# frozen_string_literal: true
# The purpose of this code is to transform legacy `database.yml`
# into a `database.yml` containing `main:` as a name of a first database
#
# This should be removed once all places using legacy `database.yml`
# are fixed. The likely moment to remove this check is the %14.0.
#
# This converts the following syntax:
#
# production:
# adapter: postgresql
# database: gitlabhq_production
# username: git
# password: "secure password"
# host: localhost
#
# Into:
#
# production:
# main:
# adapter: postgresql
# database: gitlabhq_production
# username: git
# password: "secure password"
# host: localhost
