As per the SQL specification, LIKE only works with String data type
(http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt search for "Like
predicate") .
If it has been set to PVarchar.isCoercible() that means anything which can
be coerced to Varchar but is not varchar for example VarBinary and JSON, can
also be used with "Like".
IMHO Like should only work with Varhcar and char datatype and throw illegal
data type error with other datatype arguments.
> Like operator should throw proper exception when it is used with data type
> other then Varcahr and Char
