When the transfer tool is migrating a database from a source to a destination, and the source contains a primary key, the statement is mis-typed for the destination. A typical database create statement will look like this:
create table t (i integer, constraint primary primary (i));
Note how keyword PRIMARY has been double AND note how the constraint name is missing.
