No password in making database connection

[William1104]

Dear Sir,

gp-common-go-libs/dbconn/dbconn.go

Line 198 in 39fae54

connStr := fmt.Sprintf("postgres://%s@%s:%d/%s?sslmode=disable", dbconn.User, dbconn.Host, dbconn.Port, dbconn.DBName)

It seems that we cannot provide any password for making database connection. If we secure greenplum database by disabling all 'trust' and 'ident' authentication method in 'pg_hba.conf' configuration, how may we use tools like gpbackup and gprestore (which depending on this gp-common-go-libs) ?

Thanks and regards,
William
