Hello I am returning to topic, that I opened with discussion about enhancing protocol to support access to host variables.
There was a second idea about joining host variables and session variables. This can be implemented without protocol enhancing, but it is only one way tool - we are able read host parameters only on start - but we can simply forward changes of session variables to host. I have another idea - just for psql. We can define two commands to copy psql variable to server and from server to psql. This mechanism is very simple and robust. There is not problem with security or some unwanted overhead. \vf hostvar [ sessionvar ] -- variable forward \vl hostvar [ sessionvar ] -- variable load Name of session variable is optional, when is not specified, then "host"."hostvar" is used. Ideas, comments? Regards Pavel -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
