IMHO, I'm not sure we should allow connections without the exact name
being provided. In that sense, I think we might want to consider
outright rejecting the estblishment of a connection when the given
database name doesn't fit the startup packet, since the database with
the exact given name cannot be found.

While it is somewhat off-topic, I cannot establish a connection if the
console encoding differs from the template database even if I provide
the identical database name. (I don't mean I want that behavior to be
"fix"ed.)

regards.
