Apparently you've not found pg_read_file() ?

Yes. I very strongly doubt that we'd accept a url-fetching function at
all. Aside from the security issues, it would necessarily pull in a
boatload of dependencies that we'd prefer not to have.
Of course, you can write such a thing trivially in plperlu or several
other untrusted PLs, and include any security restrictions you see fit
while you're at it. I'm not seeing how a built-in function that would
have to impose one-size-fits-all security requirements would be an
improvement.
