Subject: Use correct macro for accessing offset numbers.
Date: Sun, 11 Jan 2026 16:21:43 +0500
Message-ID: <CALdSSPidtC7j3MwhkqRj0K2hyp36ztnnjSt6qzGxQtiePR1dzw@mail.gmail.com> (raw)

Hi hackers!

While working on pageinspect support for GIN and SpGiST (welcome to
review them [0] & [1]), I spotted $subi.

PFA trivial patch that uses UInt16GetDatum for OffsetNumber rather
than Int16GetDatum
