If you mean emulate the pg_dump, no. pg_dump does a *lot* of stuff behind
the scenes, and trying to rewrite all that in Perl would be madness. And I
say that having written some serious madness into DBD::Pg already :). Stick
with the shell script, even if it means calling system.
If you simply want to avoid the pipes, you can think about calling pg_dump
from the remote box, using a authorized_keys with a specific command in it,
and other tricks, but nothing will be as straightforward and error proof
as the line you gave, I suspect.
