pgsql: Update wording: < the table.

Log Message:
-----------
Update wording:

<   the table. Another option is to avoid transaction logging entirely
<   and truncate or drop the table on crash recovery.  These should be
<   implemented using ALTER TABLE, e.g. ALTER TABLE PERSISTENCE [ DROP |
<   TRUNCATE | STABLE | DEFAULT ].  [wallog]
>   the table.  This would affect COPY, and perhaps INSERT/UPDATE too.
