The endterm attribute is mainly useful when the toolchain does not support automatic link target text generation for a particular situation. In the past, this was required by the man page tools for all reference page links, but that is no longer the case, and it now actually gets in the way of proper automatic link text generation. The only remaining use cases are currently xrefs to refsects.

You must own the operator class to use <command>ALTER OPERATOR CLASS</>.
|
|
To alter the owner, you must also be a direct or indirect member of the new
|
|
owning role, and that role must have <literal>CREATE</literal> privilege on
|
|
the operator class's schema. (These restrictions enforce that altering the
|
|
owner doesn't do anything you couldn't do by dropping and recreating the
|
|
operator class. However, a superuser can alter ownership of any operator
|
|
class anyway.)
