# 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
