I noticed that query cancellation was not working when connecting through pgbouncer,
even though it worked fine when directly connected. This is because we're appending an
extra null byte, and pgbouncer is strict about the packet length.
(per http://www.postgresql.org/docs/9.1/static/protocol-message-formats.html)
This removes the extraneous byte, which fixes cancellation against pgbouncer.
When a __prepared statement__ has no body in the query the backend responds with an `emptyQuery` message but never with a `commandComplete` or `errorResponse` message. The client was hanging forever waiting for one of the other two expected messages. The server was hanging forever waiting for the client to respond with a `sync` message. This change has the client send the required `sync` on receipt of an `emptyQuery` message when the query is a prepared statement. Fixes#822
Postgres has a 63 character limit on query names. To avoid potential footgunning of users we'll log to their stderr if they use a longer query name.
For reference: https://github.com/brianc/node-postgres/pull/772
The code is failing with pg-copy-streams. The pg-copy-streams creates a query object but it doesn't have any _result. Make the type parser an optional only when _result object available on query then only set the type parser.
Fixes a case where you connect & immediatley disconnect and _sometimes_ your notification subscription starts the reader on the libpq instance after the libpq instance is disconnected. This segfaults the app.
This completes the port from the old native bindings to the new node-pg-native bindings!
Time to build in support for older versions of postgres & start the pull request process.
Adds a check in the error listener on the client in the pool, to
prevent calling destroy on a client when it is already being
destroyed.
Without this check, if an error occurs during the ending of the
stream, such as a timeout, the client is never removed from
the pool and weird things happen.
