I don't know what the DBI/DBD design philosophy is regarding
database-specific extensions --- but it would seem reasonable to me
for DBD::Pg to offer some way to get at LISTEN functionality. Can
anyone suggest how to do this in the context of DBI?
I suggest moving any followups to pgsql-interfaces, where this
discussion would be more on-topic.
