Amount Semantics
Returns the provider's available amount text when supplied. This can differ from the booked balance amount because it reflects provider-side availability rules.
NULL means the materialized balance row has no available-amount field.
Notes
Passing NULL for in_balance is allowed and returns NULL.
NULL means the provider did not supply this optional field for the row.
The returned pointer is borrowed from the owning backend result envelope and becomes invalid when that envelope is destroyed.
