What's the best way to copy a subset of a table's rows from one database to another in Postgres?

Question

I\'ve got a production DB with, say, ten million rows. I\'d like to extract the 10,000 or so rows from the past hour off of production and copy them to my local box. How do I do

Answer 1

source server:

BEGIN;

CREATE TEMP TABLE mmm_your_table_here AS
    SELECT * FROM your_table_here WHERE your_condition_here;

COPY mmm_your_table_here TO 'u:\\source.copy';

ROLLBACK;

your local box:

-- your_destination_table_here must be created first on your box

COPY your_destination_table_here FROM 'u:\\source.copy';
