pgsql: Reword the sentence for pg_logical_slot_peek_changes function.

Reword the sentence for pg_logical_slot_peek_changes function.

Previously the duplicated paragraphs were used next to each other
in the document to demonstrate that the changes in the stream
were not consumed by pg_logical_slot_peek_changes function.
But some users misunderstood that the duplication of the same
paragraph was just typo. So this commit rewords the sentence in
the latter paragraph for less confusing.
