Should I reuse Npgsql connections in a C# application?

Hi:

I've got a C# method that, during it's course of execution, is running several queries using npgsql.
I have several queries to gather data from different sources (tables), and then a query to insert
the results into a separate table.

Is it best in this scenario to reuse the NpgsqlConnection for all the queries, or use a
separate NpgsqlConnection for each query.

I'm new to npgsql and not sure what the best practice would be in terms of
performance and reliability.

Thanks,
JohnB

that would mean that we try to reduce the opened connection to your database, and we certainly hope that in one connection request, we finished all the tasks as possible as we can. and we probably can do it via database's stored procedures. (meaning do your stuff at database end)

It's better to reuse the same connection.  There's overhead associated with opening a new connection.  If it's already open, might as well use it.

I'm new to postgresql, so I just wanted to make sure standard DB strategies still apply.
Thx!
