Copy a table from one database to another in Postgres

Question

I am trying to copy an entire table from one database to another in Postgres. Any suggestions?

Answer 1

Using dblink would be more convenient!

truncate table tableA;

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