Well, actually, just ordinary 3 tier architecture. Simple UI connected via restful API with backend written in php, which copies some data in a remote database, that's pretty much it.

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?

There are bulk copy routines available.  What is your architecture? 

    We generally "bottom
      post" in this group.
      
      Most things I find on the web suggest send the csv file to server
      and run COPY there.  Some show iterating over the csv, but
      critical to get csv off the client.
