Your problem is not simple, and that's not an adequate description of
it, because you are omitting the influence of context on what the
parameter gets typed as.
The real point here is that the JDBC driver is doing something to prompt
the parser to resolve the types of parameter symbols in particular ways,
and (I gather) you're doing something different. If you want to match
the results they get, then you need to supply the same type information
for parameter symbols to SPI_prepare as they put into Parse messages.
