Fix some bogus direct uses of realloc().
pg_dump/parallel.c was using realloc() directly with no error check. While the odds of an actual failure here seem pretty low, Coverity complains about it, so fix by using pg_realloc() instead. While looking for other instances, I noticed a couple of places in psql that hadn't gotten the memo about the availability of pg_realloc. These aren't bugs, since they did have error checks, but verbosely inconsistent code is not a good thing. Back-patch as far as 9.3. 9.2 did not have pg_dump/parallel.c, nor did it have pg_realloc available in all frontend code.
