# Extending the underlying dataset  (http://sequel.jeremyevans.net/rdoc/files/README_rdoc.html#label-Extending+the+underlying+dataset)

# The recommended way to implement table-wide logic by defining methods on the dataset using dataset_module:

    class Post < Sequel::Model
      dataset_module do
        def posts_with_few_comments

# This patch detects {index_columns} that match something like
# the example below, then strips the surrounding double quotes.
#
#   "(settings->'example')"

#
#   CREATE INDEX "idx_users_on_settings_example" ON "users" USING gin ((settings->>'example'))
#
# Your {add_index} call should looks something like:

# first:
lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do  sudo rm /usr/local/${f}; done
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:

# go to /usr/local/lib and delete any node and node_modules
cd /usr/local/lib
sudo rm -rf node*
