Bug reference: 18112
Logged by: Bo Chen
Email address: bchen90@163.com
PostgreSQL version: 15.2
Operating system: euleros
Description:
I found pgstattuple of sequence will be failed but not PG11.x, for the code
of pgstattuple it looks like still support of sequence, but the
"rel->rd_rel->relam now is 0, not HEAP_TABLE_AM_OID", so the error report
postgres=# drop Sequence test;
DROP SEQUENCE
postgres=# create Sequence test;
CREATE SEQUENCE
postgres=# select pgstattuple('test');
ERROR: SQLSTATE 0A000: only heap AM is supported
LOCATION: pgstat_heap, pgstattuple.c:322
postgres=#

OK, but so what? I mean, what useful information are you extracting
using pgstattuple from a sequence? What decisions can you make based on
these results?
