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.

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.

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

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

ALTER <thing> [IF EXISTS] ... allows silent DDL if required, e.g. ALTER FOREIGN TABLE IF EXISTS foo RENAME TO bar Pavel Stehule
On 19t of January, Magnus Hagander committed patch:
Separate state from query string in pg_stat_activity
This separates the state (running/idle/idleintransaction etc) into
it's own field ("state"), and leaves the query field containing just
query text.
The query text will now mean "current query" when a query is running
and "last query" in other states. Accordingly,the field has been
renamed from current_query to query.
Since backwards compatibility was broken anyway to make that, the procpid
field has also been renamed to pid - along with the same field in
pg_stat_replication for consistency.

On 19t of January, Heikki Linnakangas committed patch:
Make pg_relation_size() and friends return NULL if the object doesn't exist. That avoids errors when the functions are used in queries like "SELECT pg_relation_size(oid) FROM pg_class", and a table is dropped concurrently. Phil Sorber
