Hello all,

I just noticed that you can do something like this (using 9.4.1):

   select array[1,2,3] - 3

which is doing the same thing as:

   select array_remove(array[1,2,3],3)

but the minus is not documented as an array operator: http://www.postgresql.org/docs/current/static/functions-array.html

Is that an oversight in the documentation or isn't the minus supposed to work like that in the first place?

​You very likely have an intarray extension installed​:​
int[] - int  operator documented in the extension documentation as it's a part of the extension but not part of the PostgreSQL core.​
