Tom Lane abcb32d55e Improve documentation about PRIMARY KEY constraints. ... Get rid of the false implication that PRIMARY KEY is exactly equivalent to UNIQUE + NOT NULL. That was more-or-less true at one time in our implementation, but the standard doesn't say that, and we've grown various features (many of them required by spec) that treat a pkey differently from less-formal constraints. Per recent discussion on pgsql-general. I failed to resist the temptation to do some other wordsmithing in the same area.		2016-02-07 16:02:44 -05:00
