another section if required by the platform (instead of the old way of building them in section "l" and always transforming them to the platform-specific section). This speeds up the installation on common platforms, and it avoids some funny business with the man page tools and build process.

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.)
