This commit fixes a couple of issues related to the way password verifiers hashed with MD5 or SCRAM-SHA-256 are detected, leading to being able to store in catalogs passwords which do not follow the supported hash formats: - A MD5-hashed entry was checked based on if its header uses "md5" and if the string length matches what is expected. Unfortunately the code never checked if the hash only used hexadecimal characters, as reported by Tom Lane. - A SCRAM-hashed entry was checked based on only its header, which should be "SCRAM-SHA-256$", but it never checked for any fields afterwards, as reported by Jonathan Katz. Backpatch down to v10, which is where SCRAM has been introduced, and where password verifiers in plain format have been removed.
