4.1.2 not work: func (o *LargeObjects) Open(...) (*LargeObject, error)

[ghost]

in code use Prepare queries
but in function "func (q *Query) Sanitize(args ...interface{}) (string, error)" return error "unused argument: 0"
as in:

len(q.Parts) == 1
q.Parts[0] == "lo_open"

this is true for all functions in large_objects.go

Thanks for the good example. The problem was an incompatibility between prefer simple protocol and large objects. It has been fixed and test cases added.
