# Title: Allow organism to have same assembly default, accession but different base_count.
#
# Description: Remove the assembly_idx on assembly_default and assembly_accession, create new assembly_idx including base_count. The assembly can be the same but the underlying sequence have changed (e.g: new MT, new scaffolds..)
DROP INDEX assembly_idx on assembly;
ALTER TABLE assembly ADD UNIQUE assembly_idx (assembly_accession,assembly_default,base_count);
