The Oracle backend currently specifies `supports_sequence_reset = False`.
It looks as though it's been this way since the flag was added to the
Oracle backend since https://github.com/django/django/commit/0df4593f0ed.
This commit appears to have been for the 1.5 release [1] which was
released in Feb 2013. A few months later Oracle 12.1 [2] was released in
July 2013. It's quite hard to determine when `ALTER SEQUENCE … RESTART`
support was introduced but from some pain-staking searching I found that
apparently 12.1 included support for it but it wasn't documented until 18c
[3]:
> There is a new option for altering a sequence that appeared in 12.1 but
was not documented until 18c:
> `alter SEQUENCE [schema_name.]{sequence_name} restart;`
