pgAlerter

[dpremus]

Hello

I am using your ODAC components and everything works fine,
now I am planing to buy your pgDAC components, but I have
some question.

Does pgDAC works without libpq.dll on lazarus (FPC) ?

What mechanism pgAlerter use to retrive alert from server,
(constant periodically polling, long pooling (comet) or some other
push technology) ?

I need to show some sensor status real-time because
i need to consider If pgAlerter can do that or pgAlerter
will produce some extra network traffic. Now I am using
UDP for that purpose.

PgDAC installed on Lazarus doesn't require libpq.dll for connection to PostgreSQL.
