Additional non-security issues/improvements spotted by Coverity. In backend/libpq, no sense trying to protect against port->hba being NULL after we've already dereferenced it in the switch() statement. Prevent against possible overflow due to 32bit arithmitic in basebackup throttling (not yet released, so no security concern). Remove nonsensical check of array pointer against NULL in procarray.c, looks to be a holdover from 9.1 and earlier when there were pointers being used but now it's just an array. Remove pointer check-against-NULL in tsearch/spell.c as we had already dereferenced it above (in the strcmp()). Remove dead code from adt/orderedsetaggs.c, isnull is checked immediately after each tuplesort_getdatum() call and if true we return, so no point checking it again down at the bottom. Remove recently added minor error-condition memory leak in pg_regress.
