-- 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.
