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 – 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.

Waiting for 9.2 – Trigger Depth

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.

Change in anonymization of plans on explain.depesz.com

As you perhaps know, explain.depesz.com has anonymization feature.

Couple of days ago Filip contacted me and sent a patch that stopped anonymization of typecasts.

I thought about the patch, and what it achieves, changed it's internals, but kept the effect. And today, it got released.
