# Title: Remove the "species_tree" column from the species_tree_root table
#
# Description:
#   The "species_tree" column was used to keep a stringified version of the
#   tree (in newick) which hides the fact that the true structure is kept in
#   the species_tree_node table. In fact very few pipelines needed to have
#   the string there, and they can certainly reconstruct it using the API.


ALTER TABLE species_tree_root DROP COLUMN species_tree;

# Patch identifier
INSERT INTO meta (species_id, meta_key, meta_value)
  VALUES (NULL, 'patch', 'patch_85_86_b.sql|species_tree_root.species_tree');
