could not create unique index "idx_xs_item_cache_lookup"

[Daniel Drucker]

Upon upgrading to 1.10.0 (from 1.9.2.2), I get dozens of messages like:

xnat-db-1         | 2026-05-07 14:45:42.420 UTC [43] ERROR:  could not create unique index "idx_xs_item_cache_lookup"

xnat-db-1         | 2026-05-07 14:45:42.420 UTC [43] DETAIL:  Key (elementname, ids)=(xdat:user, 178) is duplicated.

xnat-db-1         | 2026-05-07 14:45:42.434 UTC [42] ERROR:  could not create unique index "idx_xs_item_cache_lookup"

However, XNAT seems to be running fine. Should I be concerned?
