Fix bogus code in contrib/ tsearch dictionary examples.
Both dict_int and dict_xsyn were blithely assuming that whatever memorypalloc gives back will be pre-zeroed. This would typically work forjust about long enough to run their regression tests, and no longer :-(.The pre-9.0 code in dict_xsyn was even lamer than that, as it wouldhappily give back a pointer to the result of palloc(0), encouragingits caller to access off the end of memory. Again, this would justbarely fail to fail as long as memory contained nothing but zeroes.Per a report from Rodrigo Hjort that code based on these examplesdidn't work reliably.
