When I execute a Valentina Dump of a test database I get this:
CREATE TABLE "Test" (
"Test" LONG NOT NULL UNIQUE INDEXED);
I believe is should be this:
CREATE TABLE "Test" (
"Test" LONG PRIMARY KEY NOT NULL UNIQUE INDEXED);
Is the dump missing the Primary Key?

If there is an existing Primary Key (PK) then you must remove the primary
key to have any other candidates.
I can remove the primary key notation on a field - VStudio errors out and
any subsequent attempt to create a primary key errors out in the same way.
I Believe, the existing field has to be Long, Unique, indexed, and NOT NULL
to be a candidate.
And the existing data must match the Unique attribute. i.e. no duplicate
data.
