Subject: pgsql: Replace literal 0 with InvalidXLogRecPtr for XLogRecPtr assignme
Date: Thu, 29 Jan 2026 17:44:32 +0000
Message-ID: <E1vlW4F-00011e-3C@gemulon.postgresql.org> (raw)

Replace literal 0 with InvalidXLogRecPtr for XLogRecPtr assignments

Use the proper constant InvalidXLogRecPtr instead of literal 0 when
assigning XLogRecPtr variables and struct fields.

This improves code clarity by making it explicit that these are
invalid LSN values rather than ambiguous zero literals.
