Hi,

This is a follow-up to the issue described in thread

In short, during the first transaction starting phase within a backend, if
there is an 'ereport' after setting transaction state but before saving
CurrentUserId into 'prevUser' in TransactionStateData, 'prevUser' will remain
as InvalidOid. Then in AbortTransaction(), CurrentUserId is restored with
'prevUser'. As a result, CurrentUserId will be InvalidOid in the rest of the
session.

Attached is a patch that fixes this issue.

Thanks
Richard
