I believe this text is false on too many accounts. So, what's the
consensus
about Inheritance in PostgreSQL, I am going to give a talk on it in
November
and I wouldn't like to advertise/promote/teach something that the
community
has decided to abandon or drop. Actually I proposed several topics
and they
chose this one (Inheritance).
There are several things wrong with table inheritance; see [1] in our
docs, in addition to the things that the wiki page notes. I think it's
good advice to stay clear of it, and if you're giving a talk, do not
talk about inheritance except to mention its drawbacks. Regarding your
talk, I would strongly suggest to ask them to choose another topic from
your list.
Yes, those limitations are known, and must be dealt. The wiki IMHO is
aggressive and insulting plus the advice to use FK instead of
inheritance is at least laughable. I don't think there should be such an
official text on the official PostgreSQL site.
I don't know enough to say either way. What I do know is that this is
the Wiki and you can sign up to edit it.
Thanks!
