[mike.tig.as][mta] server configuration

This gist contains the nginx and tor configurations for the [mike.tig.as][mta] servers, mainly to show:

• Use of the chris-lea/nginx-devel PPA to allow use of SPDY.
• ssl_ciphers selection to mitigate BEAST attack, enable [perfect forward secrecy][pfs] if possible and select the strongest possible ciphers within those bounds. (Exception is made for several ciphers at the end of list, for compatibility reasons.)

Postgres lacks convenient operators for modifying JSON or JSONB values. A common operation one might want to do is to change one property in a JSON column across multiple rows, like:

UPDATE example SET json_col = json_col || '{ "prop": true }'::jsonb WHERE <conditions>;

The || operator is the natural choice for this because it is also used for array and jstore concatenation in Postgres.

This short PLV8 function adds the JSON concatenation operator. It is significantly more powerful than the array and hstore counterparts, and are capable of:
