[Haskell-cafe] The ping method in HDBC

Hi, there I'm wondering if there's a ping method in HDBC that does the same thing as Perl DBI's ping. Please see the following link for details: http://search.cpan.org/~timb/DBI-1.605/DBI.pm#ping I think It's rather important for database auto-connection when preserving database connections for a quite long time in fastcgi applications. Any ideas? Thanks in advance! -agentzh
