Transfer data between databases with PostgreSQL

Question

I need to transfer some data from another database. The old database is called paw1.moviesDB and the new database is paw1. The schema of each table are the following.

I just had to do this exact thing so I figured I'd post the recipe here. This assumes that both databases are on the same server.

First, copy the table from the old db to the new db (because apparently you can't move data between databases). At the commandline:

pg_dump -U postgres -t   | psql -U postgres -d 

# Just adding extra space here so scrollbar doesn't hide the command

Next, grant permissions of the copied table to the user of the new database. Log into psql:

psql -U postgres -d 

ALTER TABLE  OWNER TO ;

\q

Finally, copy data from the old table to the new table. Log in as the new user and then:

INSERT INTO  (field1, field2, field3) 
SELECT field1, field2, field3 from ;

Done!
