I use numeric array columns with DBD::Pg.  What do you define as "support"?

I plan to use text arrays.

I have an old O'Reilly "Programming the Perl DBI" and it doesn't mention supoprt of these things.  I suppose that this
mightbe because some DBs don't support them. But PG does, and I was wondering how it would pass column data which is an
arraywhen using something like fetchall_arrayref().  Is there a doc for this somewhere?  I googled around for a while
anddidn't see anything. 

Thanks

Best thing to do is look up the documentation on cpan for the version you
have.

http://search.cpan.org/~turnstep/DBD-Pg-2.15.1/Pg.pm#Array_support

Has been there since 2.0.0.
