Today, I released new version of OmniPITR – 0.5.0.
This new version has one important new feature – which is so called “direct destination" for backups.
What it means? What it does? How it helps? Let's see…

Waiting for 9.2 – More rewrite-less ALTER TABLE ALTER TYPEs
Three patches for you today, all committed by Robert Hass:
- On 7th of February, patch:
Add a transform function for numeric typmod coercisions. This enables ALTER TABLE to skip table and index rebuilds when a column is changed to an unconstrained numeric, or when the scale is unchanged and the precision does not decrease. Noah Misch, with a few stylistic changes and a fix for an OID collision by me.
- also on 7th, patch:
Add a transform function for varbit typmod coercisions. This enables ALTER TABLE to skip table and index rebuilds when the new type is unconstraint varbit, or when the allowable number of bits is not decreasing. Noah Misch, with review and a fix for an OID collision by me.
- and a day later final patch:
Add transform functions for various temporal typmod coercisions. This enables ALTER TABLE to skip table and index rebuilds in some cases. Noah Misch, with trivial changes by me.

Waiting for 9.2 – EXPLAIN TIMING
On 7th of February, Robert Haas committed patch:
Sometimes it may be useful to get actual row counts out of EXPLAIN (ANALYZE) without paying the cost of timing every node entry/exit. With this patch, you can say EXPLAIN (ANALYZE, TIMING OFF) to get that. Tomas Vondra, reviewed by Eric Theise, with minor doc changes by me.
Waiting for 9.2 – Named parameters in SQL functions
On 5th of February, Tom Lane committed patch:
Allow SQL-language functions to reference parameters by name. Matthew Draper, reviewed by Hitoshi Harada

Waiting for 9.2 – JSON
On 31st of January, Robert Haas committed patch:
Like the XML data type, we simply store JSON data as text, after checking that it is valid. More complex operations such as canonicalization and comparison may come later, but this is enough for not. There are a few open issues here, such as whether we should attempt to detect UTF-8 surrogate pairs represented as \uXXXX\uYYYY, but this gets the basic framework in place.
and then, 3 days later, Andrew Dunstan committed another one, related:
Also move the escape_json function from explain.c to json.c where it seems to belong. Andrew Dunstan, Reviewd by Abhijit Menon-Sen.
Waiting for 9.2 – deadlock counter
On 26th of January, Magnus Hagander committed patch:
Adds a counter that tracks number of deadlocks that occurred in each database to pg_stat_database. Magnus Hagander, reviewed by Jaime Casanova
Waiting for 9.2 – temporary file stats per database
On 26th of January, Magnus Hagander committed patch:
Add counters for number and size of temporary files used for spill-to-disk queries for each database to the pg_stat_database view. Tomas Vondra, review by Magnus Hagander

Waiting for 9.2 – pg_basebackup from slave
On 25th of January, Simon Riggs committed patch:
Allow pg_basebackup from standby node with safety checking. Base backup follows recommended procedure, plus goes to great lengths to ensure that partial page writes are avoided. Jun Ishizuka and Fujii Masao, with minor modifications
Waiting for 9.2 – Trigger Depth
On 25th of January, Alvaro Herrera committed patch:
Add pg_trigger_depth() function This reports the depth level of triggers currently in execution, or zero if not called from inside a trigger. No catversion bump in this patch, but you have to initdb if you want access to the new function. Author: Kevin Grittner
Waiting for 9.2 – ALTER IF EXISTS
On 23th of January, Simon Riggs committed patch:
ALTER <thing> [IF EXISTS] ... allows silent DDL if required, e.g. ALTER FOREIGN TABLE IF EXISTS foo RENAME TO bar Pavel Stehule
