​I'd suggest dollar-quoting if going this route - the possibility of the
json containing single quotes is significantly large to warrant it.

[...] VALUES(1,$$json$
{...}
$json$);

In Linux we'd do:

(backticks used below)
\set json_var `cat json_file.txt`
INSERT INTO tbl (json_col) VALUES (:'json_var');

​Not sure about Windows though​.
