I don't know, how can we prevent it. Discussed verbally.

At first, there is no way to control this state as you propose.
Next, disabling/enabling triggers is required for upgrade() functionality
and is not a part of public API. As in further patches ck constraint are rely
on trigger machinery, we don't need a separate controller.
So, I've reject xfer optimization when source or destination space has
ck constraints.

Look at the EXPRDUP_REDUCE comment in sqlExprDup:
* If the EXPRDUP_REDUCE flag is set, then the structure returned is a
* truncated version of the usual Expr structure that will be stored as
* part of the in-memory representation of the database schema.
Such version doesn't contain space_def pointer by definition and we want to prevent it.

It is really redundant.

In previous review you asked, why do I inconsistently uppercase check keyword in OP_Halt;
But now I believe that it is not required: all this errors are changed in the next patch.

No we don't have xfer optimization.

I've appended a few testcases inspired by sql-tap tests.
But, you know, this coverage already exists.

Yes, you are. Fix for 2.1.0 migration contained everything what required.
===============================================
This patch introduces a new system space to persist check
constraints. Format of the space:
_ck_constraint (space id = 357)
[<constraint name> STR, <space id> UINT, <expression string>STR]
CK constraint is local to space, so every pair <CK name, space id>
is unique (and it is PK in _ck_constraint space).
After insertion into this space, a new instance describing check
constraint is created. Check constraint holds AST of expression
representing it.
While space features check constraints, it isn't allowed to
be dropped. The :drop() space method firstly deletes all check
constraints and then removes entry from _space.
Because space alter, index alter and space truncate operations
cause space recreation, introduced RebuildCkConstrains object
that compile new ck constraint objects, replace and remove
existent instances atomically(when some compilation fails,
nothing changed). In fact, in scope of this patch we don't
really need to recreate ck_constraint object in such situations
(patch space_def pointer in AST like we did it before is enough
now, but we would recompile VDBE that represents ck constraint
in future that can fail).
The main motivation for these changes is the ability to support
ADD CHECK CONSTRAINT operation in the future. CK constraints are
are easier to manage as self-sustained objects: we mustn't
the tuple describing target space to do it(unlike the current
architecture).
Disabled xfer optimization when some space have ck constraints
because in the following patches this xfer optimisation becomes
impossible. No reason to rewrite this code.
Needed for #3691

2.21.0
This patch introduces a new system space to persist check
constraints. Format of the space:
_ck_constraint (space id = 357)
[<constraint name> STR, <space id> UINT, <expression string>STR]
CK constraint is local to space, so every pair <CK name, space id>
is unique (and it is PK in _ck_constraint space).
After insertion into this space, a new instance describing check
constraint is created. Check constraint holds AST of expression
representing it.
While space features check constraints, it isn't allowed to
be dropped. The :drop() space method firstly deletes all check
constraints and then removes entry from _space.
Because space alter, index alter and space truncate operations
cause space recreation, introduced RebuildCkConstrains object
that compile new ck constraint objects, replace and remove
existent instances atomically(when some compilation fails,
nothing changed). In fact, in scope of this patch we don't
really need to recreate ck_constraint object in such situations
(patch space_def pointer in AST like we did it before is enough
now, but we would recompile VDBE that represents ck constraint
in future that can fail).
The main motivation for these changes is the ability to support
ADD CHECK CONSTRAINT operation in the future. CK constraints are
are easier to manage as self-sustained objects: we mustn't
the tuple describing target space to do it(unlike the current
architecture).
Disabled xfer optimization when some space have ck constraints
because in the following patches this xfer optimisation becomes
impossible. No reason to rewrite this code.
Needed for #3691
