Oops, fixed.

"results in an empty set" here means "the result of the evaluation is
an empty set", similar to:

$ git grep "results in an" doc
doc/src/sgml/charset.sgml:    results in an error, because even though
the <literal>||</literal> operator
doc/src/sgml/plpgsql.sgml:       an omitted <literal>ELSE</literal>
clause results in an error rather
doc/src/sgml/plpython.sgml:    If the second <literal>UPDATE</literal>
statement results in an
doc/src/sgml/pltcl.sgml:     If the second <command>UPDATE</command>
statement results in an

Maybe I could just replace that by "returns an empty set".

Will push shortly after making those changes.
