-        expression exceeding which planner will try to lookup and group
-        multiple similar <literal>OR</literal> expressions to
-        <literal>ANY</literal> (<xref linkend="functions-comparisons-any-some"/>)
-        expressions.  The grouping technique of this transformation is based
-        on the equivalence of variable sides.  One side of such an expression
-        must be a constant clause, and the other must contain a variable
-        clause.  The default value is <literal>5</literal>.  The value of
-        <literal>-1</literal> completely disables the transformation.

-        The advantage of this <literal>OR-to-ANY</literal> transformation is
-        faster query planning and execution.  In certain cases, this
-        transformation also leads to more effective plans containing
-        a single index scan instead of multiple bitmap scans.  However, it
-        may also cause a planning regression when distinct
-        <literal>OR</literal> arguments are better to match to distinct indexes.
-        This may happen when they have different matching partial indexes or
-        have different distributions of other columns used in the query.
-        Generally, more groupable <literal>OR</literal> arguments mean that
-        transformation will be more likely to win than to lose.

-        For example, this query has its set of five <literal>OR</literal>
-        expressions transformed to <literal>ANY</literal> with the default
-        value of <varname>or_to_any_transform_limit</varname>.  But not with
-        the increased value.
