<para>

|
<command>ALTER GROUP</command> changes the attributes of a user group.
|
|
This is an obsolete command, though still accepted for backwards
|
|
compatibility, because groups (and users too) have been superseded by the
|
|
more general concept of roles.
|
|
</para>
|
|
|
|
<para>
|
|
The first two variants add users to a group or remove them from a group.
|
|
(Any role can play the part of either a <quote>user</> or a
|
|
<quote>group</> for this purpose.) These variants are effectively
|
|
equivalent to granting or revoking membership in the role named as the
|
|
<quote>group</>; so the preferred way to do this is to use
|
|
<xref linkend="SQL-GRANT" endterm="SQL-GRANT-title"> or
|
|
<xref linkend="SQL-REVOKE" endterm="SQL-REVOKE-title">.
|
|
</para>
|
|
|
|
<para>
|
|
The third variant changes the name of the group. This is exactly
|
|
equivalent to renaming the role with
|
|
<xref linkend="sql-alterrole" endterm="sql-alterrole-title">.
