how to copy table one database to another database in postgresql

Have tried searching this in google[^] prior to post here?

To execute a query in remote database you can use dblink[^]

insert into mytable
select *
from dblink('dbname=postgres hostaddr=xxx.xxx.xxx.xxx dbname=mydb user=postgres',
            'select a,b from mytable')
       as t1(a text,b text);

Or, you can also use pg_dump to do that.

pg_dump -t table_to_copy source_db | psql target_db

Hope, it helps :)
