Fix for commit3c86223c99. That commit moved the typedef of pg_int64 from postgres_ext.h to libpq-fe.h, because the only remaining place where it might be used is libpq users, and since the type is obsolete, the intent was to limit its scope. The problem is that if someone builds an extension against an older (pre-PG18) server version and a new (PG18) libpq, they might get two typedefs, depending on include file order. This is not allowed under C99, so they might get warnings or errors, depending on the compiler and options. The underlying types might also be different (e.g., long int vs. long long int), which would also lead to errors. This scenario is plausible when using the standard Debian packaging, which provides only the newest libpq but per-major-version server packages. The fix is to undo that part of commit3c86223c99. That way, the typedef is in the same header file across versions. At least, this is the safest fix doable before PostgreSQL 18 releases.
