+Subject: [PATCH] Add compatibilty wrapper functions for base64
+ encoding/decoding
+
+PG13 adds a destination length 4th argument to pg_b64_decode and
+pg_b64_encode functions so this patch adds a macro that translates
+to the 3 argument and 4 argument calls depending on postgres version.
+This patch also adds checking of return values for those functions.
