prepared queries

The current release of DBD::Pg contains this in the CHANGES file:
       - $dbh->prepare() rewrites the SQL statement into an internal form,               striping out comments and
whitespace,and if PostgreSQL > 7.3 takes the               stripped statement and passes that to Postgres' PREPARE 
 
statement,               then rewrites the statement as 'EXECUTE 
"DBD::PG::cached_query n"               ($1, $2, ... $n, $n+1)' for DBD::Pg's execute.               -- Currently
disableduntil PREPARE works a little better
 

Is there a TODO here, or is it just that the Driver is a bit out of date?

Perhaps one of these items relates to the matter?:

. Allow clients to query a list of WITH HOLD cursors and prepared statements
. Allow libpq to return information about prepared queries

It's a pity if such an important client as DBD:Pg can't really use PQs. 
Is the problem that you need to supply the data types of the params at 
PREPARE time rather than discovering them from the result of a PREPARE?
