Hello,
The function timestamptz_to_str() in src/bin/pg_waldump/compat.c does not handle the case when localtime() returns NULL, which can happen for timestamps that are out of the supported time_t range on some platforms.
This patch adds a simple check for a NULL return value and ensures that the function returns a clear error string "(timestamp out of range)" instead of causing undefined behavior or a crash.
I think we can just return a static const string, without copying the string into “buf" as the function returns a “const char *”.
Best regards,
