Fix to_tsquery() and websearch_to_tsquery() to properly parse certain discarded tokens in quotes (Alexander Korotkov)

Certain discarded tokens, like underscore, caused the output of these functions to produce incorrect tsquery output, e.g., websearch_to_tsquery('"pg_class pg"') used to output '( pg &amp; class )
&lt;-&gt; pg',but now outputs 'pg &lt;-&gt; class &lt;-&gt; pg'.

Previously it was md5. All new passwords will be stored as SHA256 unless this server variable is changed or the password is already md5-hashed.
Also, the legacy (and undocumented) boolean-like values which were previously synonyms of <literal>md5</literal> are no longer accepted.
