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.
