The JDBC driver does not trim spaces. What it does is pass setString()
values with a type of varchar, perhaps pljava is using text and exposing
this subtle difference:
# select 'a '::char(2) = 'a '::text;
?column?
----------
f
(1 row)
# select 'a '::char(2) = 'a '::varchar;
?column?
----------
t
(1 row)
