Re: [HACKERS] Development Plans

I'd like to add my personal opinion on development plans,
not regarding the pure coding, but the contour instead.
(I'm not a real PG expert, so I'm limited to this).

As a university teacher, I feel the lack of introductory and explanatory
material for postgresql.
I think it would be really good if somebody really expert can prepare
videos and slides and share it on the web site. Possibly in english, but
with some sort of subtitles in the case of videos.

This is not just to cover the normal topics of Postgresql, but instead
also something regarding migration issues, development plannings, etc...
I mean, some sort of documentation that is not just barely how to use
it, but something derived from the direct experience in real world
applications.

I don't know if these considerations fit in the subject of this thread,
but I think that having a development path can be very valuable if that
path is shared and simply explained to "nobrainers" or normal students
and users.

Thanks

Simone
