Please find attached a patch which makes it possible to disallow UPDATEs and DELETEs which lack a WHERE clause. As this changes query behavior, I've made the new GUCs PGC_SUSET.
What say?
Thanks to Gurjeet Singh for the idea and Andrew Gierth for the tips implementing.
I am sending review of this patch
1. there are not any problem with patching, compiling, doc
2. the patch is simple, the documentation is good enough
3. all regress tests passed without problems
My questions:
1. is a data file really necessary? INSERT INTO test_require_where VALUES('aaa') has same effect.
2. There is not documented a assert "Assert(query->jointree != NULL)"
