GitLab requires the PostgreSQL extension '#{extension}' installed in database '#{dbname}', but
the database user is not allowed to install the extension.
You can either install the extension manually using a database superuser:
CREATE EXTENSION IF NOT EXISTS #{extension}
Or, you can solve this by logging in to the GitLab
database (#{dbname}) using a superuser and running:
ALTER #{user} WITH SUPERUSER
This query will grant the user superuser permissions, ensuring any database extensions
can be installed through migrations.
For more information, refer to https://docs.gitlab.com/ee/install/postgresql_extensions.html.

def drop_extension(extension)
execute("DROP EXTENSION IF EXISTS #{extension}")
rescue ActiveRecord::StatementInvalid => e
dbname = ApplicationRecord.database.database_name
user = ApplicationRecord.database.username
warn(<<~MSG) if e.to_s.include?('permission denied')
This migration attempts to drop the PostgreSQL extension '#{extension}'
installed in database '#{dbname}', but the database user is not allowed
to drop the extension.
You can either drop the extension manually using a database superuser:
DROP EXTENSION IF EXISTS #{extension}
Or, you can solve this by logging in to the GitLab
database (#{dbname}) using a superuser and running:
ALTER #{user} WITH SUPERUSER
This query will grant the user superuser permissions, ensuring any database extensions
can be dropped through migrations.
