Ah, yes, after re-reading the doc, I found:

The syntax of the CREATE FUNCTION command requires the function body to be written as a string constant. It is usually
mostconvenient to use dollar quoting (see Section 4.1.2.2) for the string constant. If you choose to use regular
single-quotedstring constant syntax, you must double single quote marks (') and backslashes (\) (assuming escape string
syntax)in the body of the function (see Section 4.1.2.1).

I really missed it. Sorry for making noise.
