Add a `NewWithListener` constructor to `riverdatabasesql` that allows the `database/sql` driver to be used with a functioning listener implementation. Also add a `NewListener` constructor to the `riverpgxv5` driver to allow creating a listener with a raw pgx pool. These can be combined to allow full listener support as long as the underlying database driver supports it, even when it's used within an abstraction like `database/sql` or Bun.

Any news on this? It would be incredible to get LISTEN/NOTIFY using the standard driver! |

Indeed, this would be nice to have. Is this being worked on? |

Building on #351, this PR allows users to take advantage of the new
riverdatabasesqldriver while also keeping full support forLISTENand avoiding poll-only mode.This is accomplished through a
riverdatabasesql.NewWithListener()constructor that allows thedatabase/sqldriver to be used with a functioning listener implementation. Also adds ariverpgxv5.NewListener()constructor to allow creating a listener with a raw pgx pool.These can be combined to allow full listener support as long as the underlying database driver supports it, even when it's used within an abstraction like
database/sqlor Bun.Needs tests if we want to proceed with this. I'm pleased with how little code it took to achieve though!
You could imagine this being used in the future with a non-Postgres listener implementation such as Redis, though for that to work we may need to loosen notifications to be emitted outside of a transaction (and may not be able to emit them automatically at all for the
*Txinsert variants bc we cannot tell when a transaction completes).
