I was thinking that maybe this should be a new feature in an existing tool, however I don't think pg_ctl would satisfy my use case as it's normally bundled with the server. This would need to be something that I could install just a client package. It's not a deal breaker, but it makes things more complex. How about adding it as an option to psql? That's not to say that I think we shouldn't also add it to 'pg_ctl status'. > > -- > Bruce Momjian <br...@momjian.us> http://momjian.us > EnterpriseDB http://enterprisedb.com > > + It's impossible for everything to be true. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
