What's new in PostgreSQL 9.2

Hi,

I've finished writing the "What's new" for 9.2. Here it is:

https://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.2

Please, proof-read it, English isn't my native language.

As usual, I had to make choices about what to present here. If your
favorite feature isn't here, please add it, or tell me about it :)
