Fix Read Call

Small bugfix in the decoder

Bad connection hotfix

If a connection has an error, we no longer put it back in the pool of connections, instead we remove it.

Better connection pooling

• uses the pg connection pool library (our fork - interpool)
  • allows to close all connections on exit
  • more fine grained control of pool options and driver options

Must call .Put(con) to reclaim the connection - will automatically cleanup the connection for reclamation.
