|---|
| 25 | This script is to be used to create an empty Quota Storage |
|---|
| 26 | DataBase using PostgreSQL as a backend. |
|---|
| 27 | |
|---|
| 28 | If you have already installed PyKota, and have datas in your |
|---|
| 29 | Quota Storage DataBase, you may prefer to skip this section |
|---|
| 30 | and read the next one. |
|---|
| 31 | |
|---|
| 32 | - Launch the psql frontend and connect to the |
|---|
| 33 | database template1 as a PostgreSQL administrator |
|---|
| 34 | (i.e. the postgres user) : |
|---|
| 35 | |
|---|
| 36 | $ psql -h localhost -U postgres template1 |
|---|
| 37 | |
|---|
| 38 | - Executes the pykota-postgresql.sql script : |
|---|
| 39 | |
|---|
| 40 | template1=# \i pykota-postgresql.sql |
|---|
| 41 | |
|---|
| 42 | - Quit the psql frontend : |
|---|
| 43 | |
|---|
| 44 | template1=# \q |
|---|
| 45 | |
|---|
| 46 | - Your PostgreSQL PyKota storage is now ready |
|---|
| 47 | for use. |

| 51 | Upgrade script : |
|---|
| 52 | |
|---|
| 53 | An sql script to upgrade a pre-1.01 PyKota Quota Storage |
|---|
| 54 | DataBase is included, if you want to keep your datas from |
|---|
| 55 | a pre-1.01 PyKota version, then please launch the following |
|---|
| 56 | commands : |
|---|
| 57 | |
|---|
| 58 | - Launch the psql frontend and connect to the |
|---|
| 59 | database pykota as a PostgreSQL administrator |
|---|
| 60 | (i.e. the postgres user) : |
|---|
| 61 | |
|---|
| 62 | $ psql -h localhost -U postgres pykota |
|---|
| 63 | |
|---|
| 64 | - Executes the pykota-upgrade-postgresql.sql script : |
|---|
| 65 | |
|---|
| 66 | pykota=# \i pykota-upgrade-postgresql.sql |
|---|
| 67 | |
|---|
| 68 | - Quit the psql frontend : |
|---|
| 69 | |
|---|
| 70 | pykota=# \q |
|---|
| 71 | |
|---|
| 72 | - Your PostgreSQL PyKota storage is now ready |
|---|
| 73 | for use. |
|---|
| 74 | |
|---|
| 75 | If you already run PyKota v1.01 or above, you don't need |
|---|
| 76 | to run this upgrade script. |
|---|
| 77 | |
|---|
| 78 | WARNING : |
|---|
| 79 | |
|---|
| 80 | This script requires a recent version of PostgreSQL to run |
|---|
| 81 | successfully, because it requires the ALTER TABLE DROP COLUMN |
|---|
| 82 | syntax to be supported. However in case you've got an older |
|---|
| 83 | version, upgrading PostgreSQL is not mandatory, you will just |
|---|
| 84 | have two unused fields in the grouppquota table, these |
|---|
| 85 | fields are pagecounter and lifepagecounter, just forgot them. |
|---|
| 86 | |
|---|
| 87 | IMPORTANT : |
|---|
| 88 | |
|---|
| 89 | Because the modifications are just about Group Print Quotas |
|---|
| 90 | and because Group Print Quotas are currently not fully |
|---|
| 91 | implemented, you can delay the launch of this upgrade |
|---|
| 92 | script until you really need Group Print Quotas. |
|---|
| 93 | In other terms, running this script is not mandatory |
|---|
| 94 | for PyKota to continue to work correctly, at least |
|---|
| 95 | until Group Print Quotas will be fully implemented. |
|---|
