Postgresql: How to use curl with function

问题

I have a function parse_sdf(text).
When I call the function like this:

INSERT INTO test.table("Id", "Test") 
(SELECT props -> 'Id', props -> 'Test' FROM parse_sdf());

When I execute the INSERT with pgsql I want to pass as a parameter a text file which I download via curl. Like this:

INSERT INTO test.table("Id", "Test") 
(SELECT props -> 'Id', props -> 'Test' FROM parse_sdf('curl http://test/Files/text.txt'));

But it doesn't work. Is there a way to accomplish this?

UPDATE:

Postgres version: 10
Command will be executed with ExecuteSqlCommand command from Npgsql package for EF Core.
