I have been considering that, and I can see your point. Not setting
the phase has the disadvantage to set it to "initializing" when
starting the command tracking, even for a very short time, and that
could be confusing as we state in the docs that this refers to the
point where the indexes are created. So, instead, I have actually set
the phase to "build" or "validate". As we are updating three times
the same four fields (phase, table OID, index OID and index AM) for
the concurrent creation, index build and validation, I have switched
the implementation to use a multi-param update instead everywhere, and
applied it down to 12. Thanks for the report, Matthias.
