Waiting for 9.4 – Implement the FILTER clause for aggregate function calls.
On 17th of July, Noah Misch committed patch:
Implement the FILTER clause for aggregate function calls. This is SQL-standard with a few extensions, namely support for subqueries and outer references in clause expressions. catversion bump due to change in Aggref and WindowFunc. David Fetter, reviewed by Dean Rasheed.

Waiting for 9.4 – Add support for REFRESH MATERIALIZED VIEW CONCURRENTLY.
On 16th of July, Kevin Grittner committed patch:
Add support for REFRESH MATERIALIZED VIEW CONCURRENTLY. This allows reads to continue without any blocking while a REFRESH runs. The new data appears atomically as part of transaction commit. Review questioned the Assert that a matview was not a system relation. This will be addressed separately. Reviewed by Hitoshi Harada, Robert Haas, Andres Freund. Merged after review with security patch f3ab5d4.

Waiting for 9.4 – ALTER TABLE … ALTER CONSTRAINT for FKs
On 28th of June, Simon Riggs committed patch:
ALTER TABLE ... ALTER CONSTRAINT for FKs Allow constraint attributes to be altered, so the default setting of NOT DEFERRABLE can be altered to DEFERRABLE and back. Review by Abhijit Menon-Sen

Waiting for 9.3 – Support indexing of regular-expression searches in contrib/pg_trgm.
On 9th of April, Tom Lane committed patch:
Support indexing of regular-expression searches in contrib/pg_trgm. This works by extracting trigrams from the given regular expression, in generally the same spirit as the previously-existing support for LIKE searches, though of course the details are far more complicated. Currently, only GIN indexes are supported. We might be able to make it work with GiST indexes later. The implementation includes adding API functions to backend/regex/ to provide a view of the search NFA created from a regular expression. These functions are meant to be generic enough to be supportable in a standalone version of the regex library, should that ever happen. Alexander Korotkov, reviewed by Heikki Linnakangas and Tom Lane
One day later Tom Lane added support for the same operations using GiST indexes (original patch was working only with GIN).
Waiting for 9.3 – Add \watch [SEC] command to psql.

Waiting for 9.3 – Add new JSON processing functions and parser API.
On 29th of March, Andrew Dunstan committed patch:
Add new JSON processing functions and parser API. The JSON parser is converted into a recursive descent parser, and exposed for use by other modules such as extensions. The API provides hooks for all the significant parser event such as the beginning and end of objects and arrays, and providing functions to handle these hooks allows for fairly simple construction of a wide variety of JSON processing functions. A set of new basic processing functions and operators is also added, which use this API, including operations to extract array elements, object fields, get the length of arrays and the set of keys of a field, deconstruct an object into a set of key/value pairs, and create records from JSON objects and arrays of objects. Catalog version bumped. Andrew Dunstan, with some documentation assistance from Merlin Moncure.

Waiting for 9.3 – Add parallel pg_dump option.
On 24th of March, Andrew Dunstan committed patch:
Add parallel pg_dump option. New infrastructure is added which creates a set number of workers (threads on Windows, forked processes on Unix). Jobs are then handed out to these workers by the master process as needed. pg_restore is adjusted to use this new infrastructure in place of the old setup which created a new worker for each step on the fly. Parallel dumps acquire a snapshot clone in order to stay consistent, if available. The parallel option is selected by the -j / --jobs command line parameter of pg_dump. Joachim Wieland, lightly editorialized by Andrew Dunstan.

Waiting for 9.3 – Support writable foreign tables.
On 10th of March, Tom Lane committed patch:
Support writable foreign tables. This patch adds the core-system infrastructure needed to support updates on foreign tables, and extends contrib/postgres_fdw to allow updates against remote Postgres servers. There's still a great deal of room for improvement in optimization of remote updates, but at least there's basic functionality there now. KaiGai Kohei, reviewed by Alexander Korotkov and Laurenz Albe, and rather heavily revised by Tom Lane.

Waiting for 9.3 – Report pg_hba line number and contents when users fail to log in
On 10th of March, Magnus Hagander committed patch:
Report pg_hba line number and contents when users fail to log in Instead of just reporting which user failed to log in, log both the line number in the active pg_hba.conf file (which may not match reality in case the file has been edited and not reloaded) and the contents of the matching line (which will always be correct), to make it easier to debug incorrect pg_hba.conf files. The message to the client remains unchanged and does not include this information, to prevent leaking security sensitive information. Reviewed by Tom Lane and Dean Rasheed
