Re: [JDBC] JDBC String to Bool spec

I agree it should support all the types the JDBC spec says it should; and it does.  I’m focused on the CHAR/VARCHAR  to Boolean conversion.

To add to your example

CREATE TABLE testboolstring (a varchar(30));

INSERT INTO testboolstring VALUES('this is not true’);

>> ResultSet.getBoolean(1) returns FALSE

INSERT INTO testboolstring VALUES(‘1.0’);

>> ResultSet.getBoolean(1) returns TRUE

INSERT INTO testboolstring VALUES(2.2’);

>> ResultSet.getBoolean(1) returns FALSE

Since we now know the JDBC spec doesn’t support this (thanks to all of Mark Rotteveel’s sleuthing) & we know Postgres doesn’t support this.  It seems the “feature" should be removed or placed behind an option.  Postgres results in an error here and considering this is a driver tied to that database I look to that to clarify ambiguity. These examples should all result in an error.
