Probably so. Seems there is a bit of convergent evolution going on. When I
get a moment of free time, I'll check out the pgAdmin code. Can someone
shoot me a URL to the files in question? (assuming a web cvs interface).

 


http://svn.pgadmin.org/cgi-bin/viewcvs.cgi/trunk/pgadmin3/src/frm/frmMainConfig.cpp?rev=4317view=markup

This is an editor only, an expert mode (e.g. recommendations for 
different sizes/loads) would be nice.

 Sounds a little similar to what's in pgAdmin CVS right now. The
 configuration editor can retrieve the config file and display configured
 and active setting concurrently, together with explanations taken from
 pg_settings (when not run against a pgsql server but a file current
 settings are missing, comments are taken from a pg_settings csv dump).
 There's the infrastructure to give hints about all settings, with very
 few currently implemented.

Aren't most of the settings all kept in the SHOW variables anyway?



As I said, it may not be applicable to this project, but thought I would
offer. One gotcha the module makes transparent is that in older versions of
PG, the variables are returned in a different way (via RAISE). My module
will allow you to get the configuration for any connected database, for
any configuration file, and the defaults for any known version, and do
quick comparisons between them all. So you could use it to see what has
changed between a particular server and its conf file, or the differences
between two conf files, or the differences between two databases, or even show
what has changed in the default conf file from 7.4.7 and 8.0.1. It will also
allow you to rewrite the conf files in a standard way.

[PERFORM] Configurator project launched

2005-06-21 Thread Josh Berkus
Folks,

OK, I've checked in my first code module and the configurator project is 
officially launched.  Come join us at 
www.pgfoundry.org/projects/configurator

Further communications will be on the Configurator mailing list only.

from the spec:

What is the Configurator, and Why do We Need It?
-

The Configurator is a set of Perl scripts and modules which allow users and
installation programs to write a reasonable postgresql.conf for PostgreSQL
performance based on the answers to some relatively simple questions.  Its
purpose is to provide an option between the poor-performing default
configuration, and the in-depth knowledge required for hand-tuning.

Greg,



Not sure how far along you are, but I've been writing some really nifty
extensions to DBD::Pg that allow easy querying of all the current
run-time settings. Could be very useful to this project, seems to me. If
you're interested in possibly using it, let me know, I can bump it up on
my todo list.

I'm hoping to roll this into 1.44 or 1.45 or DBD::Pg.
