Bug reference:      13846
Logged by:          Paul Hester
Email address:      [email protected]
PostgreSQL version: 9.5rc1
Operating system:   Windows 10 Pro
Description:

When using an INSERT statement with an ON CONFLICT clause, if there is a
conflict, and the table being inserted into has a column defaulted to
nextval('seq'), the sequencer 'seq' is always incremented. This can quickly
and artificially consume all values of the sequencer; it behaves as if
conflict detection happens after inserts are attempted, rather than before.
