Fair, here is a patch which should handle all uses in the frontend code
so we follow this pattern consistently to encourage new code to use
these macros.

When doing this I found two things which I am ot sure what the cleanest
way to handle would be so I broke them out into separate patches.

1. What should we do about when we allocate a an array of characters?
Would it make sense to use pg_array_alloc() or would that jsut be silly?
For example:

-pad = (char *) pg_malloc(l + 1);
+pad = pg_malloc_array(char, l + 1);

2. I found a small and harmless thinko. The buffer in verify_tar_file()
is actually a char * but for some reason the code did the following:

buffer = pg_malloc(READ_CHUNK_SIZE * sizeof(uint8));

What should we do about it? Just skip the "sizof(uint8)"?
