Re: [ADMIN] Can schemas be ordered regarding their creation time ?
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 '); comment on schema users is select quote_literal(to_char(current_timestamp,'DD Mon ')); . 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'.

No, sorry, Postgres does not track creation time of database objects. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
Re: [ADMIN] Can schemas be ordered regarding their creation time ?
Thanks Tom, I will figure out then how to add a newly created schema to the schema-list to be backed up (dumped) but not directly as i expected. Cheers, A.A.
