Ok, but how do I do that? Currently I am using: _ebi_mtab_insert(rel, CStringGetTextDatum(BVEC_NULL), bin_enc); This function does not mere than hashing the 2nd passed argument (with the internal hash functions of hash.c) but each time a different hash value is returned, so I am thinking I might pass a pointer and not the real Datum. I am highly irritated now... as for now I thought I understood Datum... -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
