Can I copy from one db (via COPY) and pipe the results to a psql/COPY stmt so
I can load the data into a table in the second db 'inline' without writing to
reading from a flat file?

1) we setup a db on a local server and we created an external tablespace on a

emergency scenario
3) now we want the data back from the san
