Re: Potential vuln in example for "F.25.1.1. digest()"

The following documentation comment has been logged on the website:

Description:

Hi,
in "F.25.1.1. digest()" you suggest:

CREATE OR REPLACE FUNCTION sha1(bytea) returns text AS $$
    SELECT encode(digest($1, 'sha1'), 'hex')
$$ LANGUAGE SQL STRICT IMMUTABLE;

While this is a great example, it may expose a database app to
vulnerabilities if the attacker succeeds in overriding the function
sha1(...) in the app's user context (schema)
