Interface for a Postgres database, expressed through high-level operations that rely on exchange of multiple messages. Operations here can be executed concurrently and are non-cancelable. The structures returned here expose internals (safely) that are important for error reporting but are not generally useful for end users.

Execute a non-parameterized command (a statement that produces no rows), yielding a
Completion. This is equivalent to prepare + bind + execute but it uses the "simple"
query protocol which requires fewer message exchanges.

Execute a non-parameterized query (a statement that produces rows), yielding all rows. This is
equivalent to prepare + bind + execute but it uses the "simple" query protocol which
requires fewer message exchanges. If you wish to page or stream results you need to use the
general protocol instead.

Unfiltered stream of all asynchronous channel notifications sent to this session. In general this stream is consumed asynchronously and the associated fiber is canceled before the session ends.

Signal representing the current state of all Postgres configuration variables announced to this session. These are sent after authentication and are updated asynchronously if the runtime environment changes. The current keys are as follows (with example values), but these may change with future releases so you should be prepared to handle unexpected ones.
