I wanted to test the grouping estimation behaviour with TPCH, While testing I found some crash so I thought of reporting it. My setup detail: TPCH scale factor : 5 Applied all the patch for 21 series, and ran below queries. postgres=# analyze part; ANALYZE postgres=# CREATE STATISTICS s2 WITH (ndistinct) on (p_brand, p_type, p_size) from part; CREATE STATISTICS postgres=# analyze part; server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed. I think it should be easily reproducible, in case it's not I can send call stack or core dump. -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
