​I don't know how you'd use the quote_literal with a literal input.

PostgreSQL also offers a feature called dollar-quoting. If you place two
dollar signs surrounding an optional string before and after the text.

i.e., $txt$I've got an unescaped quote in me$txt$

These can be nested, and are particularly useful when writing function
bodies.

These and more syntax rules can be found here:
