A few points about your code:
- The tests against NULL are useless: palloc never returns NULL and
the argument to the function won't be NULL either (it's decalred
STRICT).
- Your palloc should be for more, the header may be more than one byte
VAR_HEADER_LEN or some such would be more appropriate)
- Finally, what is probably the actual problem, at no point did you
assign a length to the hash variable, ie VARLEN(hash)=foo.
Hope this helps,
