You could write a set-returning function that reads the file, and
perhaps a view on top of that. As the file is read on every invocation,
that's only practical for small tables, though.

It's likely a better idea to just COPY the table into the database
periodically, or perhaps write an external script that watches the
modification timestamp on the file and triggers a reload whenever it
changes.
