On 14th of October Tome Lane committed new patch from Itagaki Tahahiro:
Log Message: ----------- Support SQL-compliant triggers ON COLUMNS, ie fire ONLY IF certain COLUMNS are named IN the UPDATE's SET list. Note: the schema of pg_trigger has not actually changed; we've just started TO USE a COLUMN that was there ALL along. catversion bumped anyway so that this commit IS included IN the history OF potentially interesting changes TO system catalog contents. Itagaki Takahiro
Pavel Stehule – hero for everybody writing stored procedures, wrote, and later Tom Lane committed patch which adds named arguments for functions:
Log Message: ----------- Support use of function argument names to identify which actual arguments match which function parameters. The syntax uses AS, for example funcname(value AS arg1, anothervalue AS arg2) Pavel Stehule
On 7th of October Alvaro Herrera committed his own patch, which adds quite interesting possibilty:
Log Message: ----------- Make it possibly TO specify GUC params per USER AND per DATABASE. CREATE a NEW catalog pg_db_role_setting WHERE they are now stored, AND better encapsulate the code that deals WITH settings INTO its realm. The OLD datconfig AND rolconfig COLUMNS are removed. psql has gained a \drds command TO display the settings. Backwards compatibility warning: while the backwards-compatible system views still have the config COLUMNS, they no longer completely represent the configuration FOR a USER OR DATABASE. Catalog version bumped.

One of the most common (or perhaps even the most common) question people have regarding PostgreSQL, is how to change privileges for all tables.
Usually they want something like MySQL's:
GRANT ... ON DATABASE.* TO ...
Which is interesting as it is actually 2 distinct features in one:
Now, thanks to 2 new patches – we have this possibility in PostgreSQL.
October, finally. “Only" 1 month of backlog in new features in 8.5, but I'm getting there 🙂
So, on 1st of October Tom Lane committed patch by Stef Walter:
Log Message: ----------- Support "samehost" and "samenet" specifications in pg_hba.conf, by enumerating the machine's IP interfaces to look for a match. Stef Walter
For some reason I cannot find it in mailing list archive, but luckily have copy of email (without all headers unfortunately).

On 22nd of September, Tom Lane committed a patch by Petr Jelinek:
Log Message: ----------- Implement the DO statement TO support execution OF PL code WITHOUT HAVING TO CREATE a FUNCTION FOR it. PROCEDURAL languages now have an additional entry point, namely a FUNCTION TO EXECUTE an inline code block. This seemed a better design than trying TO hide the transient-ness OF the code FROM the PL. AS OF this patch, ONLY plpgsql has an inline handler, but probably people will soon WRITE handlers FOR the other standard PLs. IN passing, remove the long-dead LANCOMPILER OPTION OF CREATE LANGUAGE.
