Rémy Voet (ryv) d2cb61dd84 [IMP] core: use faster count(*) instead of count(1)
Some article supports that count(*) is more efficient than count(1):
- https://blog.jooq.org/whats-faster-count-or-count1/
- https://www.citusdata.com/blog/2016/10/12/count-performance/ (sub menu Exact Counts)

In my own test (https://github.com/ryv-odoo/odoo_scripts/blob/master/test_count.py):
indeed, we can see a small performance gain with `count(*)` (between 2%
to 4% depending the number of row).  This isn't a big improvement but the
change is small and is now more consistent with the documentation of
postgresql (https://www.postgresql.org/docs/14/functions-aggregate.html).
