I agree that it's valid improvement to add prefer-read to target_session_attr, as a means to "get a read-only session." > But the above improvement can be enhanced once the base work of GUC_REPORT > is finished. Is it already in progress in some thread, or are you trying to start from scratch?

I'm glad to hear that. Sure. I'd like to review your patch, and possibly add/modify code if necessary. Are you going to add target_server_type={primary | standby | prefer_standby} as well as add prefer-read to target_session_attr? > (I wonder which of server_type or server_role feels natural in > English.) > > > > server_type may be good as it stands with connection option > (target_server_type). Thanks, agreed. That also follows PgJDBC's targetServerType. Regards Takayuki Tsunakawa
