Hi all,

I have an application that must copy a local file in csv format to a postgres table on a remote host. The closest solution is this one (https://stackoverflow.com/a/9327519/618020). It boils down to specifying a \copy meta-command in a psql command:

psql -U %s -p %s -d %s -f - <<EOT\n here hoes a \copy meta-command \nEOT\n

and executing it. But it's quite an unnatural way to write database code. Has anything changed in the last ten years? Or, is there a better way to copy file contents in a remote database?

I'd write a small Python script, using the csv module to read the data and psycopg2 to load it.
