When you absolutely have to manually escape SQL in CakePHP 3.4.7

it should still fix some issue It's a bummer when you can't rely on someone's else code for security, because let's face it, the vast majority of folks don't do security well. Better to rely on those libraries!
But, in cases where you can't, such as perhaps this, consider a small whitelist of possibilities for the content you expect. Think about what you are expecting to see, and enforce that. In my mind, I would expect a database name to consist solely of alphabetic letters and perhaps underscores. That obviously will not cover all possible table name values (for example, databases names can have numbers too), but it is your situation that dictates what matters.
code :
if ( ! preg_match('/^[A-z][A-z_]{0,15}$/', $databasename) ) {
    # database name does not pass the project standards of alpha
    # letters and underscores only.  Likely crack attempt.
    die('No way, Joker!');   # or something more appropriate.
}
$conn->execute("DROP DATABASE $databasename");

Does that help if mapping to .aspx exist, try the solution found here to add a route to end up in *.mvc.aspx
code :
routes.Add(new Route("{controller}.mvc.aspx/{action}", new MvcRouteHandler())
{
    Defaults = new RouteValueDictionary (new{ controller = "YourController"} )
});

like below fixes the issue The stack is of a limited size, some things just won't fit in it reliably. Dynamically allocated memory also has the dynamic nature to them, where sometimes you're not sure how many objects or elements in an array you will require until some moment in time of the execution of the program.
Check out this question, it does a great job of describing possible use cases for each:

help you fix your problem A Python tuple is adapted to a Postgresql record and a list adapted to an array. That is why in this case a tuple is not valid.
But what you say in your own answer that works does not:
code :
select unnest(['BA007EWCBD43', "KA036'AGHF550", 'KA036ACBK873']);
ERROR:  syntax error at or near "["
LINE 1: select unnest(['BA007EWCBD43', "KA036'AGHF550", 'KA036ACBK87...
FROM unnest(ARRAY['BA007EWCBD43', "KA036'AGHF550", 'KA036ACBK873'])

hope this fix your issue Looking at when and how DboSource::value() is being used internally, this is the expected behavior. If it wouldn't do what it does, then values wouldn't get prepared properly for Model::save() operations.
DboSource::value() internally passes the "booleanized" value (DboSource::boolean($value, true) this already adds quotes) to PDO::quote(), where the value is going to be quoted anyways no matter what, ie 0, 1, '0', '1', true, or false, it will always return a quoted value, that is '0', '1' or even '' (for false, which is equal to 0).

will be helpful for those in need You shouldn't need to escape literals; that's what parameterised statements are for. psycopg2 supports them for both plannable statements (insert/update/delete/select) and non-plannable statements (create table, create index, ...).
You should always be using parameterised statements in preference to directly substituting literals into query strings.
