How to troubleshoot: ERROR: cache lookup failed for type?
Hello!
When reindexing a table, PostgreSQL returns the following errors for
two of its indexes:
Index foo_idx1 on foo failed with error: failed to find parent tuple
for heap-only tuple at (1162372,1) in table "foo"
Index foo_idx2 on foo failed with error: failed to find parent tuple
for heap-only tuple at (1162372,1) in table "foo"
When trying to show the tuple, there is another error message:
SET enable_indexscan = OFF;
SET enable_tidscan = OFF;
SELECT ctid, xmin, xmax, * FROM sf.dir_current_part_8 WHERE ctid =
'(1162372,1)';
ERROR: cache lookup failed for type 1769235301
Searching for oid=1769235301 in pg_class, pg_type, pg_namespace and
pg_proc returned no results.
It appears to be data corruption.
It's PostgreSQL 13 and unfortunately, data_checksums are turned off.
I would appreciate any suggestions for troubleshooting this issue.

What is the complete version number e.g. 13.x?
What prompted the reindex of the table?
Have there been any recent hardware/software issues on the machine?
Does the Postgres log have any relevant information?
Can you pg_dump -t sf.dir_current_part_8?
What is the schema definition for sf.dir_current_part_8?
I would appreciate any suggestions for troubleshooting this issue.
