### Is your feature request related to a problem or challenge? Arrow-DataFusion can support creating an array of a certain data type (`make_array`), but there are no functions to work with them. In my opinion, the documentation of the database PostgreSQL can serve as a reference for working on arrays. The following features are considered for implementation: Operators: - [ ] Any Array operators: - [ ] concatenation - [ ] overlap - [ ] concatenate Array functions: - [ ] array_append - [ ] array_cat - [ ] array_ndims - [ ] array_dims - [ ] array_fill - [ ] array_length - [ ] array_lower - [ ] array_position - [ ] array_positions - [ ] array_prepend - [ ] array_remove - [ ] array_replace - [ ] array_to_string - [ ] array_upper - [ ] cardinality - [ ] string_to_array - [ ] unnest ### Describe the solution you'd like Series of PR, active discussion of features. ### Describe alternatives you've considered The significance of some features can be disproven as a result of conversations. ### Additional context Sources: The array documentation: [PostgreSQL](https://postgrespro.ru/docs/postgrespro/15/functions-array?lang=en) #6073 #6075 -- This is an automated message from the Apache Git Service.
