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
ofthe pg_shadow table and after that copies the contents of this table to the pg_pwd ASCII file (and generates
anempty 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
createtables 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
