This is surprising. As I understand it, REINDEX scans the complete table
and builds a new index. So after a REINDEX the index should be complete
and usable.

However, reading
https://www.postgresql.org/docs/current/sql-reindex.html I'm unsure what
happens if you have issued a REINDEX for a table, schema, etc. and
rebuilding an index fails: Does it abort at that time or does it just
issue a notice and continue to rebuild the other indexes? In the latter
case it migh be easy to miss a problem.
