[Description]
The PKCS11 API key associated with the token of Slot ID was not defined at load time.
[System Processing]
This is only a warning message when TDE_h is loaded.
[Action]
The token API key must be known to tde_h before secure keys can be used. Specify the API key at load time with --api-key option, or by GUC tde_h.API_KEY in postgresql.conf. Or, specify the API key at run-time using SELECT pgx_open_keystore(API Key); or SELECT pgx_set_master_key(API Key);
