I think the problem was that msvc couldn't quite deal with VA_ARGS_NARGS. Or something like that. <tinker, curse, tinker> Ah, yes: ../src/bin/psql/tab-complete.c(4064): fatal error C1026: parser stack overflow, program too complex We discussed something around VA_ARGS_NARGS not working on windows: https://postgr.es/m/f450fc57-a147-19d0-e50c-33571c52cc13%40postgrespro.ru But now I don't immediately see the above error as being related. If I remove all the completions after /* Complete INSERT INTO with table names */ else if (TailMatches("INSERT", "INTO")) COMPLETE_WITH_SCHEMA_QUERY(Query_for_list_of_updatables); it builds with msvc as well. And when using a readline sourced from vcpkg, it even links. Of course only a few of the completions work, given that I truncated a whole lot of them away... So It might just be that we need to split up that very long "else if" chain in psql_completion(). Greetings, Andres Freund
