This is a known issue. The driver has no knowledge of dollar quotes in
its query parser. This is not just a problem for parameters, but also an
issue when people want to issue a create function command with
Statement.execute("CREATE FUNCTION f() RETURNS int AS $$ [a number of
statements separated by semicolons] $$ language plpgsql"); The driver
will detect the semicolons and try to execute each fragment separately.
So this is a know issue with the only workaround being to not use dollar
quotes.
