I've modified the patchset based on comments received on thread [1]
for the CREATE_REPLICATION_SLOT
changes. Based on the request from that thread, I've taken out those
changes as two new patches (patch-1 and patch-2)
and made this into 5 patches. I've also changed the logic to align
with the changes in the command syntax.
I've also addressed one pending comment from Amit about
CreateInitDecodingContext, I've taken out the logic that
sets slot->data.two_phase, and only kept the logic that sets ctx->twophase.
Before:
- ctx->twophase &= MyReplicationSlot->data.two_phase;
+ ctx->twophase &= (ctx->twophase_opt_given || slot->data.two_phase);
+
+ /* Mark slot to allow two_phase decoding if not already marked */
+ if (ctx->twophase && !slot->data.two_phase)
+ {
+ slot->data.two_phase = true;
+ ReplicationSlotMarkDirty();
+ ReplicationSlotSave();
+ }
After:
- ctx->twophase &= MyReplicationSlot->data.two_phase;
+ ctx->twophase &= slot->data.two_phase;
