<command>ALTER DATABASE</command> changes the attributes

2003-06-27 16:45:32 +02:00

The first two forms change the session default for a run-time
|
2003-06-27 16:45:32 +02:00
|
|
|
configuration variable for a <productname>PostgreSQL</productname>
|
|
|
|
database. Whenever a new session is subsequently started in that
|
|
|
|
database, the specified value becomes the session default value.
|
|
|
|
The database-specific default overrides whatever setting is present
|
|
|
|
in <filename>postgresql.conf</> or has been received from the
|
|
|
|
<command>postmaster</command> command line. Only the database
|
|
|
|
owner or a superuser can change the session defaults for a
|
2005-01-04 01:39:53 +01:00
|
|
|
database. Certain variables cannot be set this way, or can only be
|
|
|
|
set by a superuser.

The third form changes the name of the database. Only the database
|
2005-01-04 01:39:53 +01:00
|
|
|
owner or a superuser can rename a database; non-superuser owners must
|
|
|
|
also have the
|
2003-06-27 16:45:32 +02:00
|
|
|
<literal>CREATEDB</literal> privilege. The current database cannot
|
|
|
|
be renamed. (Connect to a different database if you need to do
|
|
|
|
that.)

can change the database's owner.

Set this database's session default for the specified configuration
|
|
|
|
parameter to the given value. If
|
2002-03-01 23:45:19 +01:00
|
|
|
<replaceable>value</replaceable> is <literal>DEFAULT</literal>
|
|
|
|
or, equivalently, <literal>RESET</literal> is used, the
|
2005-01-04 01:39:53 +01:00
|
|
|
database-specific setting is removed, so the system-wide default
|
2002-03-01 23:45:19 +01:00
|
|
|
setting will be inherited in new sessions. Use <literal>RESET
|
2005-01-04 01:39:53 +01:00
|
|
|
ALL</literal> to clear all database-specific settings.
