pgperl vs dbd-perl

I'm wondering which of the two is considered the best.  I have both
installed on my system and actually have done some work with PgPerl
because it looked a bit less complicated, and at first, I thought that
this might be a more postgres-specific interface.

However, in researching the mailing lists, etc, it seems that DBD:: is
getting the most attention - in fact, I see little mention of PgPerl,
and the PgPerl list seems rather quiet.

In addition, it appears that DBD can do things that PgPerl can't.  For
example, I haven't been able to find an escape-string function in
PgPerl, which I'm now looking to implement.  Would one need to write his
own escape-string for PgPerl?

Is PgPerl still viable or is DBD the way to go?
