Assuming I have a PG function called DoSomething with a single integer parameter, sendPreparedStatement("SELECT * FROM DoSomething(?)", BigInt(0)) worked just fine in 0.2.18 but no longer does when upgrading to 0.2.20. Now you get an error like:

[error] c.g.m.a.d.p.PostgreSQLConnection - Error with message -> ErrorMessage(fields=Map(Position -> 15, Line -> 523, Hint -> No function matches the given name and argument types. You might need to add explicit type casts., File -> parse_func.c, SQLSTATE -> 42883, Routine -> ParseFuncOrColumn, Message -> function dosomething(unknown) does not exist, Severity -> ERROR))

I assume this is because of #169.
