-- Sailline ancillary data
|
|
--
|
|
-- New schema version: 0.5.1
|
|
--
|
|
-- ATTENTION:
|
|
--
|
|
-- ENSURE YOU HAVE BACKED UP THE DATABASE BEFORE RUNNING THIS SCRIPT.
|
|
--
|
|
--
|
|
-- NOTE: This upgrade affects all schemas in the database.
|
|
-- NOTE: Each application starts a transaction, which must be committed
|
|
-- or rolled back.
|
|
--
|
|
-- The sequences_detail view wrongly associates source lines and shot
|
|
-- points when it should be associating saillines and shot points instead.
|
|
--
|
|
-- This updates fixes that issue (#307).
|
|
--
|
|
-- To apply, run as the dougal user:
|
|
--
|
|
-- psql <<EOF
|
|
-- \i $THIS_FILE
|
|
-- COMMIT;
|
|
-- EOF
|
|
--
|
|
-- NOTE: It can be applied multiple times without ill effect.
