Andres Freund	3223b3c92d	Centralized Connection Lifetime Management. Connections are tracked and released by integrating into postgres' transaction handling. That allows to to use connections without having to resort to having to disable interrupts or using PG_TRY/CATCH blocks to avoid leaking connections. This is intended to eventually replace multi_client_executor.c and connection_cache.c, and to provide the basis of a centralized transaction management. The newly introduced transaction hook should, in the future, be the only one in citus, to allow for proper ordering between operations. For now this central handler is responsible for releasing connections and resetting XactModificationLevel after a transaction.	2016-12-07 11:43:18 -08:00
