In front of the Coordinators, that's fine. But I am not sure in from
of the Datanodes as XC has one extra connection parameter to identify
the node type from which connection is from, and a couple of
additional message types to pass down transaction ID, timestamp and
snapshot data from Coordinator to Datanodes (actually Coordinators as
well for DDL queries). If those message types and/or connection
parameters get filtered by pgpool or pgbouncer, well you cannot use
them. I've personally never given a try though, but the idea is worth
an attempt to reduce lock contention that could be caused by a too
high value of max_connections.
