Обсуждение: Running config vars

Hi all (I hope this is the correct list),

Under Oracle there is v$parameter which list ALL config varables.  Under
psql there is the SHOW command, but this only lists 1 variable.  I have
written a shell script (attached) that shows ALL know variables.  My
questions is can this script get included under contrib directory and is
there a way to make it into a view.  I believe this kind of info will
help in trouble shooting problems.

thanks
Jim

I will try to get this feature into 7.2, though as backend code.

I've long been thinking that the SET/RESET/SHOW commands could be
implemented as stored procedures and/or functions.  That way you could
cleanly return the settings to the client application and compose new
values out of arbitrary expressions.  If ever functions can return
multiple rows you could also arrange for them to show all current
settings.

I added a function to the c library that I sent to patches the other day --
called "get_var". It implements what you describe above (that is, one
variable at a time). I'd like to get this into contrib, or do the work
necessary to get it into the backend -- any interest in letting me give that
a try?

Thanks,

Joe
