Bug reference:      14486
Logged by:          Per Modin
Email address:      web+postgresql@modin.io
PostgreSQL version: 9.6.1
Operating system:   Linux 303a92173594 4.8.15-moby #1 SMP Sat Dec 17 0
Description:

Found this bug in 9.4.8, tried it in docker towards psql 9.6.1 and it's in
there as well. A minimum working example would be as follows:

```
postgres=# CREATE TABLE tbl AS SELECT 9223372036854 * interval '1 second'
col; TABLE tbl;
SELECT 1
ERROR:  interval out of range
```

```
postgres=# SELECT count(*) FROM tbl;
 count
-------
     1
(1 row)
```

It seems that inserting and retrieving data have different constraints. As
you
can see from query 2, the data still gets inserted.

```
postgres=# select version();
                                         version
------------------------------------------------------------------------------------------
 PostgreSQL 9.6.1 on x86_64-pc-linux-gnu, compiled by gcc (Debian 4.9.2-10)
4.9.2, 64-bit
(1 row)
```

Best regards,
Per Modin


And these work without error:

postgres=# select col - 9223372036854 * interval '1 second' from tbl ;
 ?column?
----------
 00:00:00
(1 row)

postgres=# select col from xx where col < interval '100000 year' ;
 col
-----
(0 rows)
