pgsql: Use correct parameter name for view_option_value

Use correct parameter name for view_option_value

The documentation for ALTER VIEW had a minor copy-and-paste error in
defining the parameters.  Noticed when reviewing the WITH CHECK OPTION
patch.

Backpatch to 9.2 where this was first introduced.
