pg_basebackup with -R option and start standby have problems with escaped password

Test scenario to reproduce:
1. Start the server
2. create the user as follows
./psql postgres -c "create user user1 superuser login
password 'use''1'"

3. Take the backup with -R option as follows.
./pg_basebackup -D ../../data1 -R -U user1 -W

The following errors are occurring when the new standby on the backup
database starts.

FATAL: could not connect to the primary server: missing "=" after "1'" in
connection info string

Hari babu.
