- Only a database superuser can change privileges and password
- expiration with this command. Ordinary users can only change their
- own password.
+ The first variant of this command in the synopsis changes certain
+ global user privileges and authentication settings. (See below for
+ details.) Only a database superuser can change privileges and
+ password expiration with this command. Ordinary users can only
+ change their own password.
+
+
+ The second and the third variant change a user's session default of
+ a specified configuration variable. Whenever the user subsequently
+ starts a new session, SET
+ variable TO
+ value is effectively executed
+ before the start of the session. Ordinary users can change their
+ own session defaults. Superusers can change anyone's session
+ defaults.
+
+
+ variable
+ value
+
+ Set this user's session default of the specified configuration
+ variable to the given value. If
+ value is DEFAULT
+ or, equivalently, RESET is used, the
+ user-specific variable setting is removed and the user will
+ inherit the default setting in new sessions. Use
+ RESET ALL to clear all settings.
+
+
+ See and the
+ Administrator's Guide for more
+ information about allowed variable names and values.
+
+
+
Use
to do that.
+
+ Using
+ endterm="sql-alterdatabase-title">, it is also possible to tie a
+ session default to a specific database rather than a user.

Access privileges on procedural languages
CREATE DATABASE has OWNER option so superuser can create DB for someone else
Kerberos 5 support now works with Heimdal
+Database and user-specific session defaults of run-time configurations variables

]]>
- Finally, some options can be changed in individual SQL sessions
- with the SET command, for example
+ Some options can be changed in individual SQL sessions with the
+ SET command, for example
=> SET ENABLE_SEQSCAN TO OFF;
See the SQL command language reference for details on the syntax.
+ Furthermore, it is possible to assign a set of option settings to
+ a user or a database. Whenever a session is started, the default
+ settings for the user and database involved are loaded. The
+ commands ALTER DATABASE and ALTER
+ USER, respectively, are used to set this up.
