<p>Beginning with SQLite 3.23.0 (2018-04-02), SQLite recognizes the
identifiers "TRUE" and "FALSE" as boolean literals, if and only if those
identifiers are not already used for some other meaning.  If there already
exists columns or tables or other objects named TRUE or FALSE, then for
the sake of backwards compatibility, the TRUE and FALSE identifiers refer
to those other objects, not to the boolean values.

<p>The boolean identifiers TRUE and FALSE are usually just aliases for
the integer values 1 and 0, respectively.  However, if TRUE or FALSE
occur on the right-hand side of an IS operator, then they form new
unary postfix operators "IS TRUE" and "IS FALSE" which test the boolean
value of the operand on the left.
