Instead of checking just the first letter, match the whole string using pg_strcasecmp. Per the documentation, we allow either just the first letter (e.g. "c") or the whole name ("custom"); but we will no longer accept random variations such as "chump". This matches pg_dump's longstanding parsing code for the same option. Also for consistency with pg_dump, recognize "p"/"plain". We don't support it, but we can give a more helpful error message than "unrecognized archive format".
