The minimum set of commands I can find to recreate this are: drop table if exists tprt; create table tprt (col1 int) partition by range (col1); create table tprt_1 partition of tprt for values from (1) to (5001); create index tprt1_idx on tprt_1 (col1); insert into tprt values (10), (20), (501), (502), (505), (1001), (4500); vacuum tprt; select relname,relallvisible from pg_Class where relname like 'tprt%' and relkind = 'r'; I get relallvisible = 0 once in maybe 20 or so attempts. I didn't manage to get the same without a partitioned table. -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
