><P
>   As in Unix, groups are a way of logically grouping users to ease
   management of privileges: privileges can be granted to, or revoked
   from, a group as a whole.  To create a group, use the <A
HREF="sql-creategroup.html"
><I
>CREATE GROUP</I
></A
> SQL command:
</P><PRE
CLASS="SYNOPSIS"
>CREATE GROUP <TT
CLASS="REPLACEABLE"
><I
>name</I
></TT
>;</PRE
><P>

   To add users to or remove users from an existing group, use <A
HREF="sql-altergroup.html"
><I
>ALTER GROUP</I
></A
>:
</P><PRE
CLASS="SYNOPSIS"
>ALTER GROUP <TT
CLASS="REPLACEABLE"
><I
>name</I
></TT
> ADD USER <TT
CLASS="REPLACEABLE"
><I
>uname1</I
></TT
>, ... ;
ALTER GROUP <TT
CLASS="REPLACEABLE"
><I
>name</I
></TT
> DROP USER <TT
CLASS="REPLACEABLE"
><I
>uname1</I
></TT
>, ... ;</PRE
><P>

   To destroy a group, use <A
HREF="sql-dropgroup.html"
><I
>DROP GROUP</I
></A
>:
</P><PRE
CLASS="SYNOPSIS"
>DROP GROUP <TT
CLASS="REPLACEABLE"
><I
>name</I
></TT
>;</PRE
><P>
   This only drops the group, not its member users.
  </P
><P
>   To determine the set of existing groups, examine the <TT
CLASS="STRUCTNAME"
>pg_group</TT
>
   system catalog, for example
</P><PRE
CLASS="SYNOPSIS"
>SELECT groname FROM pg_group;</PRE
><P>

HREF="app-psql.html"

> program's <TT
CLASS="LITERAL"
>\dg</TT
> meta-command
   is also useful for listing the existing groups.
