Thank you for implementing this. Next step partial Foreign Key like in #7260

I suppose that if v4 opens an ODS 13.1 database with partial index, it may not work properly, trying to find entries in index without considering its condition, correct?

Do we consider these cases as valid for minor ODS upgrade?

v4 cannot attach an ODS 13.1 database.

✅ Build firebird 1.0.4757 completed (commit 91eb884b4f by @hvlad)

Following script causes FB crash (checked on 5.0.0.938; problem in line marked as "[ ! ]"):

set bail on;
shell del c:\temp\tmp4test.fdb 2>nul;
create database 'localhost:c:\temp\tmp4test.fdb';
show version;
set list on;
set echo on;
recreate table test(
    id int primary key
    ,f01 int
    ,f02 int
);
create index test_f01 on test computed by (f01)
where f01 = 1 --------------------------------- [ ! ]
;

@pavel-zotov Should be fixed now.

@@@ QA issue @@@
Currently this test contains only trivial cases for check.
More complex examples, including test of backup/restore, validation, using of misc datatypes (non-ascii, decfloat and int128), will be added later.
