REINDEX CONCURRENTLY unexpectedly fails - Mailing list pgsql-bugs

Hi everyone,

On the latest trunk version, I get an error "index "t0_pkey_ccnew"
already contains data" when using REINDEX CONCURRENTLY:

CREATE TEMP TABLE t0(c1 INT PRIMARY KEY) ON COMMIT DELETE ROWS;
REINDEX TABLE CONCURRENTLY t0; -- unexpected: ERROR:  index
"t0_pkey_ccnew" already contains data

Is this expected? I think I did not observe this error on earlier
PostgreSQL versions.

Best,
Manuel
