[sqlite] Problem with SQLite version 3.9.2 together with user authentication extension

[Ulrich Telle]

SQLite version 3.8.7 introduced the user authentication extension. This 
extension worked well for all 3.8.x versions.

Now I intended to upgrade to SQLite version 3.9.2. However, if I enable 
the user authentication extension using the compile time define 
SQLITE_USER_AUTHENTICATION I experience problems.

If I start with a new, empty database (using the SQLite shell), it 
should not require user authentication. However, I always get the error 
message

Error: SQL logic error or missing database

as soon as I enter for example a "create table" statement.

I tracked it down to a call of function sqlite3Parser in function 
sqlite3RunParser. The statement to be parsed is

SELECT name, rootpage, sql FROM 'main'.sqlite_master ORDER BY rowid

The call is in line 461 of tokenize.c:

sqlite3Parser(pEngine, TK_SEMI, pParse->sLastToken, pParse);

This function returns with a return code 1 in pParse->rc. And 
pParse->zErrMsg contains "user not authenticated".

Is this a bug in SQLite somewhere? Or am I doing something wrong?
