Too many clients #36

The lib works fine at startup, but after a few map movments, I get the following error :

sorry, too many clients already
server/node_modules/tilesplash/lib/index.js:236:50

When I check the max_connections of my pg database, it is set to 100. I tried to reduce the poolSize of db to 20 or so, but it does not seem to be taken into account. If I wait a little (like 30 seconds or so), the connections are terminated and the server is able to make some calls again, but then after a few moves the error pops back. If I kill and restart the server, it seems to clear the queue.

Did this happened to anyone ?

Fixed faradayio#36
aa4746d 
Currently, a pg pool was created for each request : this is bad, as each pool keeps a connection to the db so it can reuse it. This caused issue faradayio#36 for me. 
By following the example here : https://github.com/brianc/node-postgres/tree/v6.4.1 the pool must be created only once, and reused across requests (that's the purpose of a pool).
