[sqlite] result of sqlite3_finalize zero, but sqlite3_errcode produces (rightly) SQLITE_CONSTRAINT

[Bart Smissaert]

Have a simple table with a primary integer key.
Doing an insert (with no insert or ignore or insert or replace) with
duplicate values
for this primary integer key field produces zero on sqlite3_finalize, but
19 from sqlite3_errorcode.
I thought that the result value of sqlite3_finalize also should produce a
non-zero value.
This is with the latest version.
Anything I am overlooking here or misunderstanding?
