Deleting records from a remote postgresql database using locally supplied list

Question

I have the following logic in a bash script that works:

 #copy records to delete file to respective servers.  faster than running locally
 scp -o StrictHostK         


        

Answer 1

You don't need to copy the file to the server. What you're looking for is the STDIN for COPY:

cat records_to_delete.txt | psql $server -c "COPY tmp_widgets FROM STDIN;"
