Hi. Now that v17beta2 is part of my dev-env, I'm trying out the new API. And I discover there's no version macro for conditional compilation in LIBPQ... I found https://www.postgresql.org/message-id/968815.1623936849%40sss.pgh.pa.us where Tom thinks that a horrible idea, and instead proposes a new _HAS_ flag instead. Except of course there's on such flag for the new PQsocketPoll in beta2... I see only 3 such _HAS_ flags. I'm not sure what's so wrong with version macro as such. - GCC has one. - [SQLite has one][1]. - Why can't LIBPQ have one? That's exactly the kind of issues they are designed to solve for code that needs to be portable across versions. What am I missing? Thanks, --DD [1]: https://www.sqlite.org/c3ref/c_source_id.html
