Hello Álvaro,

Should we skip non-ready indexes in build_new_indexes?

Also, in the current implementation, concurrent mode is marked as
non-MVCC safe. From my point of view, this is a significant limitation
for practical use.
Should we consider an option to exchange non-MVCC issues to short
exclusive lock of ProcArrayLock + cancellation of some transactions
with older xmin?

Best regards,
Mikhail
