fyi. There is a proposed change to the meaning of the dbRecordsOnceOnly global variable under consideration.
This change would make dbRecordsOnceOnly!=0 less restrictive.

As a reminder, dbRecordsOnceOnly defaults to zero.

Currently with

> record(ai, "myrec") {}

dbRecordsOnceOnly!=0 currently disallows appending fields with either form:

> record("*", "myrec") {} # error
> record(ai, "myrec") {}  # error

This PR changes the meaning such that dbRecordsOnceOnly!=0 always allows appending when explicitly intended (rtype "*").

> record("*", "myrec") {} # allowed
> record(ai, "myrec") {}  # error
