Hackers,
This is my multi-table truncate patch. Includes doc changes and couple
new regression tests.
Note the following excerpt from the temp regression test:
+ BEGIN;
+ CREATE TEMP TABLE temptest3(col int PRIMARY KEY) ON COMMIT DELETE ROWS;
+ NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "temptest3_pkey" for table "temptest3"
+ CREATE TEMP TABLE temptest4(col int REFERENCES temptest3);
+ COMMIT;
+ ERROR: invalid ON COMMIT and foreign key combination
+ DETAIL: Table "temptest4" references "temptest3", but they don't have the same ON COMMIT setting
I haven't investigated whether we can reject the foreign-key/on-commit
combination at create table time, rather than commit time. Maybe it's
worth doing, but then apparently on-commit-actions is not used a lot
(nobody saw the bug I previously reported).
Please review and consider for application.
Thanks,
--
