+-- Upgrade the database from commit 4d977848 to 3d70a460.
+--
+-- NOTE: This upgrade must be applied to every schema in the database.
+-- NOTE: Each application starts a transaction, which must be committed
+-- or rolled back.
+--
+-- This adds the `meta` column to the output of the following views:
+--
+--  * raw_lines_summary; and
+--  * sequences_summary
+--  
+-- To apply, run as the dougal user, for every schema in the database:
+--
+-- psql <<EOF
+-- SET search_path TO survey_*,public;
+-- \i $THIS_FILE
+-- COMMIT;
+-- EOF
+--
+-- NOTE: It can be applied multiple times without ill effect.
