OK, our consensus is that dblink should be replaced with SQL/MED interface
and then we'll start to consider integrating into core.
However, automatic transaction management needs help by core. Is it
acceptable to have two-phase callbacks? Registered callbacks are
called with TWOPHASE_EVENT_PRE_COMMIT when a transaction is about
to be committed or prepared. The argument gxact is NULL if the
transaction is committed without 2PC.
typedef enum
{
TWOPHASE_EVENT_PRE_COMMIT,
TWOPHASE_EVENT_POST_COMMIT,
TWOPHASE_EVENT_POST_ABORT,
TWOPHASE_EVENT_RECOVER,
} TwoPhaseEvent;
typedef void (*TwoPhaseEventCallback) (
TwoPhaseEvent event, GlobalTransaction gxact, void *arg);
