There is a good doc about this at:

Hi guys,

I installed PostgreSQL without readline
(--without-readline), but how can add the readline
support right now??

Am I supposed to reconfigure/make/make install to do
that????

PostgreSQL supports triggers which let you implement it yourself.
Luckily for you and I, someone else has already done most of the work
and made a documentation set for it.

Hi Esteban,

Postgres doesn't support materialized views, although I think there was
some talk of implementing them a few months ago. Try searching
pgsql.ru about this.

There are several possible present alternatives, depending on your
situation. First off, if your query on a view is running too slowly,
look into optimizing the query itself to make it as fast as possible.
If it's still too slow, and if either your data are relatively static
or you don't need up-to-the-minute accuracy, the simplest solution is
probably to just turn the view into a static table via "create table t as
select * from v", then update that table periodically. This usually
works well enough for my needs.

If you need up-to-the-minute accuracy, you could turn the view itself
into a table, then create triggers or rules on the tables used by the
view to keep everything synched.

So the answer really depends on how the view is defined, what you
plan to use it for, and how often your database is updated.

Yes. Maybe you can recompile only psql to save some time ...
