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Is there a TODO here, or is it just that the Driver is a bit out of date?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