Changes the definition of a protocol.
ALTER PROTOCOL name RENAME TO newname ALTER PROTOCOL name OWNER TO newowner
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.
- The name (optionally schema-qualified) of an existing protocol.
- The new name of the protocol.
- The new owner of the protocol.
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;
There is no ALTER PROTOCOL statement in the SQL standard.
