| |This patch fixes a backend crash that happens sometimes when you try to |join on a field that contains NULL in some rows. Postgres tries to |compute a hash value of the field you're joining on, but when the field |is NULL, the pointer it thinks is pointing to the data is really just |pointing to random memory. This forces the hash value of NULL to be 0. | |It seems that nothing matches NULL on joins, even other NULL's (with or |without this patch). Is that what's supposed to happen? | |
