Waiting for 9.1 – triggers on views
On 10th of October, Tom Lane committed patch by Deal Rasheed, which adds triggers on views:
Support triggers on views. This patch adds the SQL-standard concept of an INSTEAD OF trigger, which is fired instead of performing a physical insert/update/delete. The trigger function is passed the entire old and/or new rows of the view, and must figure out what to do to the underlying tables to implement the update. So this feature can be used to implement updatable views using trigger programming style rather than rule hacking. In passing, this patch corrects the names of some columns in the information_schema.triggers view. It seems the SQL committee renamed them somewhere between SQL:99 and SQL:2003. Dean Rasheed, reviewed by Bernd Helmle; some additional hacking by me.

Waiting for 9.1 – Recognize functional dependency on primary keys.
Yesterday (August, 7th), Tom Lane committed:
Log Message: ----------- Recognize functional dependency on primary keys. This allows a table's other columns to be referenced without listing them in GROUP BY, so long as the primary key column(s) are listed in GROUP BY. Eventually we should also allow functional dependency on a UNIQUE constraint when the columns are marked NOT NULL, but that has to wait until NOT NULL constraints are represented in pg_constraint, because we need to have pg_constraint OIDs for all the conditions needed to ensure functional dependency. Peter Eisentraut, reviewed by Alex Hunsaker and Tom Lane

Waiting for 9.1 – Reduced lock levels for ALTER TABLE
On 28th of July, Simon Riggs committed patch which:
Log Message: ----------- Reduce lock levels of CREATE TRIGGER and some ALTER TABLE, CREATE RULE actions. Avoid hard-coding lockmode used for many altering DDL commands, allowing easier future changes of lock levels. Implementation of initial analysis on DDL sub-commands, so that many lock levels are now at ShareUpdateExclusiveLock or ShareRowExclusiveLock, allowing certain DDL not to block reads/writes. First of number of planned changes in this area; additional docs required when full project complete.

Waiting for 9.1 – standard_conforming_strings = on
Generally I write about new features, but this change is relatively important.
Yesterday, on 20th of July, Robert Haas committed following change:
Log Message: ----------- Change the default value of standard_conforming_strings to on. This change should be publicized to driver maintainers at once and release-noted as an incompatibility with previous releases.

Waiting for 9.0 – Final Post ?
As of now, I am happy user of 9.1devel version of PostgreSQL:
=$ psql -c 'select version()' version --------------------------------------------------------------------------------------------------------------------- PostgreSQL 9.1devel on x86_64-unknown-linux-gnu, compiled by GCC gcc-4.4.real (Ubuntu 4.4.3-4ubuntu5) 4.4.3, 64-bit (1 row)
So, I guess no new features will make it to 9.0 – after all, 9.0 is currently already beta3.
If you want to get list of what I wrote about for 8.5/9.0 – just check the tag page.
