[gold-users] Question on the g_transaction_log table.

Well, the reason is that the database subroutines which checkpoint to the log are update, delete and undelete. And since these calls are never normally performed against the transaction object, no entries ever go into the transaction log.
However, your question has caused me to wonder if it is a mistake that insert is not checkpointing to the journal. I will have to examine this and also evaluate the impact to performance if we were to checkpoint all transaction inserts. I think we would probably want to exclude the transaction log from insert checkpoints anyhow.
Thanks for bringing this up. I will try to examine this in the last phase of the next gen Gold development actions.
