Description
Per https://www.sqlite.org/lang_altertable.html
ALTER TABLE RENAME COLUMNis supported since 3.25 but had issues with unique columns until 3.27ALTER TABLE ADD COLUMNis supported since 3.2.0 not sure why it wasn't used in the first place since 3.2 was released in 2005?ALTER TABLE DROP COLUMNwill be supported by 3.35
This will leave only ALTER COLUMN and ADD/REMOVE CONSTRAINT that must be emulated on SQLite 3.35+
