Agreed. We can refactor the code later if needed.
The patch looks good to me except the following minor points.
* or not. Normal path through RecordTransactionCommit() will be related* to a transaction commit XLog record, and so
shouldpass "false" here.
The above source comment of TransactionTreeSetCommitTsData() seems to
need to be updated.
+ * Note: if you change this functions you should also look at
+ * RecordTransactionCommitPrepared in twophase.c.
Typo: "this functions" should be "this function"
+ if (replorigin_sesssion_origin == InvalidRepOriginId ||
This is not the problem of the patch, but I started wondering what
"sesssion" in the variable name "replorigin_sesssion_origin" means.
Is it just a typo and it should be "session"? Or it's the abbreviation
of something?
