No, there's no "short periods", this is what it shows. That's partly because the output is designed for pg_dump to use. But there's a reasonably good argument for it anyway, which is that if you just say "create index" then that's effectively a macro for building the whole partitioned index set. That pg_indexes entry is only about the top-level "virtual" index, and there are other entries for the leaf indexes. For example, regression=# create table foo (f1 int primary key) partition by list (f1); CREATE TABLE regression=# create table foo_1 partition of foo for values in (1); CREATE TABLE regression=# create table foo_2 partition of foo for values in (2); CREATE TABLE regression=# select tablename,indexname,indexdef from pg_indexes where indexname like 'foo%'; tablename | indexname | indexdef -----------+------------+------------------------------------------------------------------ foo | foo_pkey | CREATE UNIQUE INDEX foo_pkey ON ONLY public.foo USING btree (f1) foo_1 | foo_1_pkey | CREATE UNIQUE INDEX foo_1_pkey ON public.foo_1 USING btree (f1) foo_2 | foo_2_pkey | CREATE UNIQUE INDEX foo_2_pkey ON public.foo_2 USING btree (f1) (3 rows) If you wanted to reconstruct this from individual parts, as pg_dump does, you'd issue those commands and then connect them together with ATTACH PARTITION commands. regards, tom lane
