Abort operations on request abort

[strk]

When client aborts the connection we want to stop doing our work.
See #76

What do you mean by "stop doing our work"?

I guess one of the things you propose is to cancel queries to postgres (specially the ones going through mapnik). What else?

[strk]

Those going trough mapnik, those going directly though the PSQL module. An any work which is outside of PostgreSQL (like formatting outputs). The more we stop doing the better.

Not waiting for responses from abort requests might be a good idea (I'm thinking about clients that abort due to client timeout and any of our database interactions, including cancels, queued in pgbouncer due to a backend crash...)
