Обсуждение: Support of type procedure

Hi,

I have read in some document about Postgres that this last supports
attrubutes of type procedure.
Type procedure allows values of an attribute to be represented by a
procedure.
I don't find an example wich illustrate this.
Please can someone give me some exemples.

Thank you for your help.

best regards,

Mourad.

This presumably existed in or near Berkeley POSTGRES 4.2, and some support
code is still there, but it probably doesn't work anymore, nor is there a
syntax that allows you to create such a thing.
