There are two questions in the pgsql-admin mailing list which are very often
asked, but nobody seems to have a reasonable answer to these.
So I decided to post them here and I hope anyone can help me (and many
others) !


    - Can a PostgreSQL user change his own password without having
      "usesuper" set to 't' in pg_shadow ?

      I think this should be possible with a PostgreSQL C function (or
      PL/Tcl) which alters the "passwd" attribute of the pg_shadow table and
      after that copies the contents of this table to the pg_pwd ASCII file
      (and generates an empty pg_pwd.reload).
      But I have no idea how to manipulate and copy tables within PostgreSQL
      C functions.

      Does anybody know if there is already such a function or any other way
      to achieve the above mentioned functionality ?


    - Can the Postgres superuser prevent a user from creating tables in any
      database the user likes to ?

      It would be good to have a way to restrict the use of the "CREATE
      TABLE" SQL statement so that a user can only create tables in
      databases he is explicitly allowed to.

      Does anyone have an idea how to solve this problem ?


If these two features are not yet implemented I would suggest to think about
implementing them, because I (and many other people) would consider them
as important, especially in practical use.

Please let me know !


Thank you very much
