Problem:
Need to Dump Table user_data_login and restore it at Server-B from Server-A
DataBase Name: users_DB
User: postgres
At Server A
as postgres user
pg_dump --table=user_data_login users_DB -f /tmp/users_data.sql
At Server B
assuming that the users_DB.sql has been copied at /tmp/users_data.sql
execute the command below as postgres user
psql -d users_DB -f /tmp/users_data.sql
that's it.
