[BioSQL-l] bioperl-db bugs

[Hilmar Lapp]

Hi Chris,

I added comments to both bug reports. This belongs to BioPerl,  
though, as it has only to do with its language binding.

The tidbit may be worth keeping in mind for a general BioSQL audience  
is that bioentry namespace (foreign key to biodatabase) is part of  
the (compound) bioentry unique keys. The identifier column used to be  
unique by itself (and could still be made such in a local instance,  
there's a comment to this effect in the DDL), but that was changed a  
while ago. (Also, if one uses any of the Bio* language bindings,  
changing a unique key constraint to something that differs from what  
the language binding assumes may be asking for a lot of trouble.  
Bioperl-db will expect the combination of primary_id() and namespace 
() to match if the latter is provided.)
