I believe the use cases for this are narrow. Generally, clients set the application_name and then don't need to retrieve it. Its primary use seems to be on the server-side, for monitoring through pg_stat_activity. Could you explain your use case? Assuming we do require this functionality, should we then also consider the interplay between application_name and fallback_application_name? Additionally, if a SET application_name TO xxx command is issued during a subsequent connection, will the appname field within the PGconn structure be updated promptly? -- Regrads, Japin Li
