-- Fix wrong number of missing shots in summary views

|
|
-- New schema version: 0.4.0
|
|
--
|
|
-- 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.
|
|
--
|
|
-- This adapts the schema to the change in how project configurations are
|
|
-- handled (https://gitlab.com/wgp/dougal/software/-/merge_requests/29)
|
|
-- by creating a project_configuration() function which returns the
|
|
-- current project's configuration data.
|
|
--
|
|
-- To apply, run as the dougal user:
|
|
--
|
|
-- psql <<EOF
|
|
-- \i $THIS_FILE
|
|
-- COMMIT;
|
|
-- EOF
|
|
--
|
|
-- NOTE: It can be applied multiple times without ill effect.
