Use an improved definition for "disqualified" initiatives
"initiative"."disqualified" is TRUE, if the initiative may not win, because it either (a) has no better rank than the status quo, or (b) because there exists a better ranked initiative X, which directly beats this initiative, and either more voters prefer X to this initiative than voters preferring X to the status quo or less voters prefer this initiative to X than voters preferring the status quo to X

| jbe@0 | 2 Setup the database: |
| jbe@0 | 3 $ createdb liquid_feedback |
| jbe@0 | 4 $ psql -v ON_ERROR_STOP=1 -f core.sql liquid_feedback |
| jbe@0 | 5 |
| jbe@0 | 6 Optionally insert demo data: |
| jbe@0 | 7 $ psql -v ON_ERROR_STOP=1 -f demo.sql liquid_feedback |
| jbe@0 | 8 |
| jbe@0 | 9 Compile lf_update binary: |
| jbe@0 | 10 $ make |
| jbe@0 | 11 |
| jbe@0 | 12 If you wish, copy the created lf_update file to /usr/local/bin or a |
| jbe@0 | 13 similar directory. Ensure that "lf_update dbname=liquid_feedback" |
| jbe@0 | 14 is called regularly. On successful run, lf_update will not produce |
| jbe@0 | 15 any output and exit with code 0. |
| jbe@0 | 16 |
| jbe@0 | 17 NOTE: When writing to the database, some INSERTs must be executed |
| jbe@0 | 18 within the same transaction, e.g. issues can't exist without |
| jbe@0 | 19 an initiative and vice versa. |
| jbe@0 | 20 |
| jbe@8 | 21 To create an export file, which is containing all but private data, |
| jbe@8 | 22 you may use the lf_export shell-script: |
| jbe@8 | 23 $ lf_export liquid_feedback export.sql.gz |
| jbe@8 | 24 |
| jbe@0 | 25 To uninstall the software, delete the lf_update binary |
| jbe@0 | 26 and drop the database by entering the following command: |
| jbe@0 | 27 $ dropdb liquid_feedback |
| jbe@0 | 28 |
| jbe@120 | 29 Updating is done using the update scripts in the update/ directory. |
| jbe@120 | 30 After updating it is recommended to recreate the schema as follows: |
| jbe@120 | 31 $ pg_dump --disable-triggers --data-only DATABASE_NAME > tmp.sql |
| jbe@120 | 32 $ dropdb DATABASE_NAME |
| jbe@120 | 33 $ createdb DATABASE_NAME |
| jbe@120 | 34 $ psql -v ON_ERROR_STOP=1 -f core.sql DATABASE_NAME |
| jbe@120 | 35 $ psql -v ON_ERROR_STOP=1 -f tmp.sql DATABASE_NAME |
| jbe@120 | 36 $ rm tmp.sql |
| jbe@120 | 37 |
