* Get rid of unnecessary memory allocation in jsonb_subscript_assign()Alexander Korotkov2021-02-01
| | | | Current code allocates memory for JsonbValue, but it could be placed locally.
* Fix portability issue in new jsonbsubs code.Tom Lane2021-02-01
| | | | | | | | | On machines where sizeof(Datum) > sizeof(Oid) (that is, any 64-bit platform), the previous coding would compute a misaligned workspace->index pointer if nupper is odd. Architectures where misaligned access is a hard no-no would then fail. This appears to explain why thorntail is unhappy but other buildfarm members are not.
* Implementation of subscripting for jsonbAlexander Korotkov2021-01-31
Subscripting for jsonb does not support slices, does not have a limit for the number of subscripts, and an assignment expects a replace value to have jsonb type. There is also one functional difference between assignment via subscripting and assignment via jsonb_set(). When an original jsonb container is NULL, the subscripting replaces it with an empty jsonb and proceeds with an assignment. For the sake of code reuse, we rearrange some parts of jsonb functionality to allow the usage of the same functions for jsonb_set and assign subscripting operation. The original idea belongs to Oleg Bartunov. Catversion is bumped.
