The data types that contrib/pageinspect's bt_metap() function were
declared to return as OUT arguments were wrong in some cases. In
particular, the oldest_xact column (a TransactionId/xid field) was
declared integer/int4 within the pageinspect extension's sql file. This
led to errors when an oldest_xact value that exceeded 2^31-1 was
encountered.
We cannot fix the declaration on Postgres 11 or 12. All we can do is
ameliorate the problem. Use "%d" instead of "%u" to format the output
of the oldest_xact value. This makes the C code match the declaration,
suppressing unhelpful error messages that might otherwise make
bt_metap() totally unusable. A bogus negative oldest_xact value will be
displayed instead of raising an error.
