If we want to preserve the possibility to except an empty string as
correct value, then pgbench should initialise some variables with
NULL instead of empty string.

Moreover it should be documented that "unspecified" means NULL and not
empty string, like in PQsetdbLogin.

However, attached you will find the whole patch, including documentation.
