To make a copy a Postgres database, log into a SSH terminal and issue the following commands. pg-user-name is the postgres database user name in these examples, so yours may differ
First dump a copy of the table to a file
pg_dump -U pg-user-name -c db_name > db_name_dump
Then create a new database
createdb -U pg-user-name db_name_2010
Then import the previously dumped file into the new database
