I think during fast forward, we also need handle the xlog that marks a transaction
as catalog modifying, or the snapshot might lose some transactions?

+ if (SnapBuildCurrentState(builder) >= SNAPBUILD_BUILDING_SNAPSHOT)
+ {
+ /* Currently only XLOG_HEAP_INPLACE means a catalog modifying */
+ if (info == XLOG_HEAP_INPLACE && TransactionIdIsValid(xid))
+ ReorderBufferXidSetCatalogChanges(ctx->reorder, xid, buf->origptr);
+ }
We only call ReorderBufferXidSetCatalogChanges() for the xlog that marks a transaction as catalog
modifying, and we don't care about the other steps being done in the xlog, so I think the current
approach is ok.
