Thanks hary and Matthias,
It is a very good idea, however the schema names are meaningful and not 
allowed to be attached to a date.
Regarding the comment solution ("COMMENT ON SCHEMA x IS 'y'"), it sounds 
great and I tried to run different examples without happy ending as 'y' 
must be a literal string.

I ran commands like these :

comment on schema users is select to_char(current_timestamp,'DD Mon YYYY');

comment on schema users is select 
quote_literal(to_char(current_timestamp,'DD Mon YYYY'));

..... and even simple concatenated strings :  comment on schema users is 
'a'||'b';
                                                                       
ERROR:  syntax error at or near "||"
                                                                       
LINE 1: comment on schema users is 'a'||'b';

... and even with a function returning a text ... : (


Any idea on doing ("COMMENT ON SCHEMA x IS 'y'") as 'y' variable?


Thanks again,
I appreciate it a lot,
A.A.




I have been trying a lot of different options to do this :

"COMMENT ON SCHEMA x IS 'y'".
