Guard against reallocation failure in pg_regress
realloc() will return NULL on a failed reallocation, so the destination pointer must be inspected to avoid null pointer dereference. Further, assigning the return value to the source pointer leak the allocation in the case of reallocation failure. Fix by using pg_realloc instead which has full error handling.
