Tom Lane c0222c2c9b Doc: clarify behavior of standard aggregates for null inputs. ... Section 4.2.7 says that unless otherwise specified, built-in aggregates ignore rows in which any input is null. This is not true of the JSON aggregates, but it wasn't documented. Fix that. Of the other entries in table 9.55, some were explicit about ignoring nulls, and some weren't; for consistency and self-contained-ness, make them all say it explicitly. Per bug #15884 from Tim Möhlmann. Back-patch to all supported branches. Discussion: https://postgr.es/m/15884-c32d848f787fcae3@postgresql.org		2019-08-27 16:37:22 -04:00
