I didn't check whether your transformation is correct, but if so then it
can be changed like this and save the extra XidDidCommit call:
xvac_committed = TransactionIdDidCommit(xvac);
if (xvac_committed)
{
/* committed */
}
else if (!TransactionIdIsInProgress(xvac))
{
if (xvac_committed)
{
/* committed */
}
else
{
/* aborted */
}
}
else
{
/* in-progress */
}
