define dsn_missing_err
CDB_DSN envvar is undefined. To run the migrations this envvar
must point to a cockroach db instance. For example, if you are
running a local cockroachdb (with --insecure) and have created
a database called 'linkgraph' you can define the envvar by 
running:

export CDB_DSN='postgresql://root@localhost:26257/linkgraph?sslmode=disable'

endef
export dsn_missing_err

check-dsn-env:
ifndef CDB_DSN
	$(error ${dsn_missing_err})
