The pgpool is an interesting approach to this, but I think that the
funcionality of inserting a record at a backend which will be
"redirectioned" to other and verifying deadlocks under network demands
in acquiring locks on the referenced records/tables in several hosts.
Then, IMO, this may be implemented inside dbms. How Marko wrote, this
is a non-trivial solution...
Really, It could be improved on pgpool to be a process coordinator,
but will need some changes in backend too.
This is a non trivial implementation, but there are several users
waiting for an effective solution for data distributing in a cluster.
These users actually buy commercial solutions or build themselves one.
