Just a thought:

1) Create a function that encapsulates the above logic where the
argument is the file name.

2) Create a shell script. Use substitution to take the filename passed
to the shell script to build a string and in the script do

psql -d db_name -U user_name -c 'select the function(filename)'

2a) Use alternate language to do 2).
