Обсуждение: pgsql: Parenthesize macro arguments safely.

Log Message:
-----------
Parenthesize macro arguments safely.  I see no bug among the current
uses of PG_DETOAST_DATUM_SLICE, but it's clearly trouble waiting to
happen.

If this is trouble waiting to happen it should probably be backported.
Otherwise a future bug fix could introduce a call to it and then be
backportted fix without anyone catching that the macro was defined
differently previously.
