Re: Doc Rework: Section 9.16.13 SQL/JSON Query Functions

+   <replaceable>context_item</replaceable> can be any character string that
+   can be succesfully cast to <type>jsonb</type>.

typo: "succesfully", should be "successfully"

maybe rephrase it to:
+   <replaceable>context_item</replaceable> can be jsonb type or any
character string that
+   can be successfully cast to <type>jsonb</type>.


+        <literal>ON EMPTY</literal> expression (that is caused by empty result
+        of <replaceable>path_expression</replaceable>evaluation).
need extra white space, should be
+        of <replaceable>path_expression</replaceable> evaluation).



+        The default when <literal>ON EMPTY</literal> or <literal>ON
ERROR</literal>
+        is not specified is to return a SQL NULL value when the respective
+        situation occurs.
Correct me if I'm wrong.
we can just say:
+        The default when <literal>ON EMPTY</literal> or <literal>ON
ERROR</literal>
+        is not specified is to return an SQL NULL value.
Anyway, this is a minor issue.
