Postgres has this too. There is a COPY command that you can find out more about through psql:

db=> \h COPY
Command:     COPY
Description: copy data between files and tables
Syntax:
COPY table [ ( column [, ...] ) ]
    FROM { 'filename' | stdin }
    [ [ WITH ] 
          [ BINARY ] 
          [ OIDS ]
          [ DELIMITER [ AS ] 'delimiter' ]
          [ NULL [ AS ] 'null string' ] ]

You can also copy a table to a file. This may not be available through DBI but you can always create the file and then system "psql < file_to_copy_in";.
