Hi, @assam258-5892
Thank you for your report! Your analysis is excellent!
> It's difficult to make a case because the data is inside the corporate
security net.
According to the source codes, I was able to construct a successful
reproduction of the issue:
```sql
create table t_issue_1222(i int4[]) with (appendonly=true);
create index t_issue_1222_idx on t_issue_1222 using gin (i)
with (fastupdate = on, gin_pending_list_limit = 4096);
insert into t_issue_1222 select array[1, 2, g] from generate_series(1,
400000) g;
CREATE TABLE
CREATE INDEX
ERROR: Unexpected internal error (assert.c:48) (seg1 127.0.1.1:9903
pid=3489454) (assert.c:48)
DETAIL:
FailedAssertion("OffsetNumberIsValid(ItemPointerGetOffsetNumber(&segment->first))",
File: "ginpostinglist.c", Line: 338)
```
I have a quick fix and a little more at

If you'd like to improve it later, feel free to do so!
