But I have the possibility to "chmod a-x" before "chmod +s" the file.

Maybe we should add "[NOT] PUBLICLY EXCUTABLE"[1] keywords to CREATE
FUNCTION, with the default being the current behaviour for now (possibly
configurable). Add an appropriate note in the docs for CREATE FUNCTION,
so users are informed about the security implications.

[1] alternative spelling proposals: "[NOT] PUBLIC" or "PUBLIC | PRIVATE"
Thinking about it, "CREATE [OR REPLACE] [PUBLIC|PRIVATE] FUNCTION ..."
seems the "most sexy" variant in my eyes.

HTH,
Markus
