control of exactly how many and when network round trips occur.
Context Support
All potentially blocking operations take a context.Context. The default behavior when a context is canceled is for the
method to immediately return. In most circumstances, this will also close the underlying connection. This behavior can
be customized by using BuildContextWatcherHandler on the Config to create a ctxwatch.Handler with different behavior.
This can be especially useful when queries that are frequently canceled and the overhead of creating new connections is
a problem. DeadlineContextWatcherHandler and CancelRequestContextWatcherHandler can be used to introduce a delay before
interrupting the query in such a way as to close the connection.
All potentially blocking operations take a context.Context. If a context is canceled while the method is in progress the
method immediately returns. In most circumstances, this will close the underlying connection.
The CancelRequest method may be used to request the PostgreSQL server cancel an in-progress query without forcing the
