I have large database and with this DB work more users and I very need

Browse Source 
more restriction for fretful users. The current PG allow define only
NO-CREATE-DB and NO-CREATE-USER restriction, but for some users I need
NO-CREATE-TABLE and NO-LOCK-TABLE.

This patch add to current code NOCREATETABLE and NOLOCKTABLE feature:

CREATE USER username
    [ WITH
     [ SYSID uid ]
     [ PASSWORD 'password' ] ]
    [ CREATEDB   | NOCREATEDB ] [ CREATEUSER | NOCREATEUSER ]
->  [ CREATETABLE | NOCREATETABLE ] [ LOCKTABLE | NOLOCKTABLE ]
    ...etc.

 If CREATETABLE or LOCKTABLE is not specific in CREATE USER command,
as default is set CREATETABLE or LOCKTABLE (true).

 A user with NOCREATETABLE restriction can't call CREATE TABLE or
SELECT INTO commands, only create temp table is allow for him.
