package postgres_async

Release v0.17.0

• Postgres_async now returns appropriate sql_state_codes for connection-related error states, such as connection unexpectedly closed.

• Postgres_async gained implementation of the SimpleQuery message flow, which is currently exposed under Postgres_async.Private, as it is relatively new and not extensively tested. If you wish to try it, the main entry points are simple_query and execute_simple.

• Postgres_async.Private.pg_cancel is a best-effort attempt to send out-of-bound message equivalent to invocation of pg_cancel_backend() for the given connection.

• Postgres_async.close now accepts an optional try_cancel_statement_before_close parameter to try and issue out-of-band cancel request for the currently running statement (if any) before closing the connection.

• For the Postgres_async.copy_in_rows and String_escaping.Copy_in, the column_names parameter type changed from string array to string list.
