postgresql - Different effects of ORDER BY clause on two servers -


my query:

select * table group id;

id field primary key, of course;

in 9.4.4 expected error:

column "table.name" must appear in group clause or used in aggregate function

but! in 9.4.5 works, in mysql.

can tell me - why? :)

postgres version not matter here. tables not identical. in 9.4.5 table column id primary key, while in 9.4.4 not.
