While checking how BM_PERMANENT flag is set (in buffer header), I noticed that
hash index has it set too. Shouldn't pg_class(relpersistence) be 'u' in this
case? Currently it's set to 'p':
postgres=# CREATE TABLE a(i int);
CREATE TABLE
postgres=# CREATE INDEX ON a USING HASH (i);
WARNING: hash indexes are not WAL-logged and their use is discouraged
CREATE INDEX
postgres=# \d a
Table "public.a"
Column | Type | Modifiers
--------+---------+-----------
i | integer |
Indexes:
"a_i_idx" hash (i)
postgres=# select relpersistence from pg_class where relname='a_i_idx';
relpersistence
----------------
p
(1 row)
