Hi, With \bind, \parse, \bind_named and \close, it is possible to issue queries from psql using the extended protocol. However, it wasn't possible to send those queries using pipelining and the only way to test pipelined queries was through pgbench's tap tests.
The attached patch adds pipelining support to psql with 3 new meta-commands, mirroring what's already done in pgbench: - \startpipeline starts a new pipeline. All extended queries will be queued until the end of the pipeline is reached. - \endpipeline ends an ongoing pipeline. All queued commands will be sent to the server and all responses will be processed by the psql. - \syncpipeline queue a synchronisation point without flushing the commands to the server Those meta-commands will allow testing pipelined query behaviour using psql regression tests.
