Just to visualize this approach. Below are the output for the tabular
form and the sentence form from last patch version (sql script attached):
Tabular form rolname | memberof | options
| grantor
------------------+------------------+---------------------+------------------ postgres
| | | regress_du_admin |
regress_du_role0+| admin, inherit, set+| postgres
+ | regress_du_role1+| admin, inherit, set+|
postgres + | regress_du_role2 | admin, inherit,
set | postgres regress_du_role0 | |
| regress_du_role1 | regress_du_role0+| admin, inherit, set+|
regress_du_admin+ | regress_du_role0+|
inherit +| regress_du_role1+ |
regress_du_role0 | set |
regress_du_role2 regress_du_role2 | regress_du_role0+|
admin +| regress_du_admin+ |
regress_du_role0+| inherit, set +|
regress_du_role1+ | regress_du_role0+|
empty +| regress_du_role2+ |
regress_du_role1 | admin, set | regress_du_admin(5
rows)Sentence form from patch v7 rolname
| memberof
------------------+-------------------------------------------------------------- postgres
| regress_du_admin | regress_du_role0 from postgres (admin, inherit,
set) + | regress_du_role1 from postgres (admin,
inherit, set) + | regress_du_role2 from postgres
(admin, inherit, set) regress_du_role0 | regress_du_role1 |
regress_du_role0 from regress_du_admin (admin, inherit,
set)+ | regress_du_role0 from regress_du_role1
(inherit) + | regress_du_role0 from
regress_du_role2 (set) regress_du_role2 | regress_du_role0 from
regress_du_admin (admin) + |
regress_du_role0 from regress_du_role1 (inherit, set)
+ | regress_du_role0 from regress_du_role2
(empty) + | regress_du_role1 from
regress_du_admin (admin, set)(5 rows)
The tabular form solves the latest patch translation problems mentioned by Kyotaro.
But it requires mapping elements between 3 array-like columns.
To move forward, needs more opinions?
