Unless I am mistaken, Perl is required in any case to build from CVS, 
although not from a tarball.

DBI/DBD::pg is quite another issue, however. I have been deliberately 
very conservative about what modules to require for the buildfarm, and 
we have similarly (and I think wisely) been conservative about what 
modules to require for Perl programs in the build process.

Using DBI/DBD::Pg would raise another issue - what version of libpq 
would it be using? Not the one in the build being tested, that's for 
sure. If you really want to use Perl then either a Pure Perl DBI driver 
(which Greg has talked about) or a thin veneer over libpq such as we 
used to have in contrib seems a safer way to go.
