Simple way of Exporting and Importing a Table

[dbuxton101]

Hey I am looking to find a way to export data from a database and import to the same structured database but on a different server.

I have managed to export the data by going
psql -U Administrator -d cc -c "COPY cntcfg TO 'C:\cntcfg.txt' DELIMITER ',' CSV;"

but when I try the import
psql -U Administrator -d cc -c "COPY cntcfg FROM 'C:\cntcfg.txt' DELIMITER ',' CSV;"

I receive an error
ERROR: duplicate key value violates unique constraint "cntcfg_stattype_cntid_tasktype_idx"
DETAIL: Key (stattype, cntid, tasktype)=(7, 8000, 1) already exists.
CONTEXT: COPY cntcfg, line 1

Please help.
