Re: Problem creating index

Interesting .....

while trying to restore the database on the same machine as different database I get this error message:

ERROR:  date/time field value out of range: "20016009:50:37.927936"

Since I get this data from a database dump obtained with "pg_dump" on the same hardware I suppose that can to be two possibility:

- postgresql bug somewhere

- hardware problem that caused data corruption

Since the dump file is 11G is not so easy to handle ....

I think that this is not related with create index problem since this field is not used by this index and increase maintenance memory had worked.

I'll fix it and go ahead in maintenance_work_mem test for index creating.

Unfortunately, since no one knows what the real problem is, we can't
make the message more clear.  Something that is never supposed to
happen has happened.

One thing you could do is set log_error_verbosity to verbose.

It seems like the most likely cause is flaky hardware, either memory
or hard-drive.  In which case, your database is in serious danger of
irrecoverable corruption.

Is it reproducible that if you lower the maintenance_work_mem you get
the error again, and if you raise it the error does not occur?

I'll try to restore the database on the same hw but different DB using differente maintenance_work_mem end verbosity and I'll posted the result here, if can help to improve the error message.
