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

From within psql, you just use copy with the query you gave us, exporting this as a CSV (or whatever format), switch database with \c and import it.

Look into \h copy in psql.
