Changes the definition of a protocol.

Synopsis

ALTER PROTOCOL <name> RENAME TO <newname>
ALTER PROTOCOL <name> OWNER TO <newowner>

Description

ALTER PROTOCOL changes the definition of a protocol. Only the protocol name or owner can be altered.

You must own the protocol to use ALTER PROTOCOL. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on schema of the conversion.

These restrictions are in place to ensure that altering the owner only makes changes that could by made by dropping and recreating the protocol. Note that a superuser can alter ownership of any protocol.

Parameters

name

The name (optionally schema-qualified) of an existing protocol.

newname

The new name of the protocol.

newowner

The new owner of the protocol.

Examples

To rename the conversion GPDBauth to GPDB_authentication:

ALTER PROTOCOL GPDBauth RENAME TO GPDB_authentication;

To change the owner of the conversion GPDB_authentication to joe:

ALTER PROTOCOL GPDB_authentication OWNER TO joe;

Compatibility

There is no ALTER PROTOCOL statement in the SQL standard.
