Quantity Semantics
Returns the held quantity as a borrowed materialized string. The quantity type is exposed separately by gln_get_holding_quantity_type.
NULL means the materialized holding row has no quantity field.
Notes
Passing NULL for in_holding 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.
