Subject: pgsql: Fix incorrect error message in xlogreader.c
Date: Sat, 05 Sep 2026 00:13:32 +0000
Message-ID: <E1x2e2F-00000003W46-0O2b@gemulon.postgresql.org> (raw)

Fix incorrect error message in xlogreader.c

When neither BKPIMAGE_HAS_HOLE nor BKPIMAGE_COMPRESSED is set,
DecodeXLogRecord() checks that bimg_len needs to be equal to BLCKSZ.
However, the associated error message reported the data length
associated to a block (DecodedBkpBlock.data_len), and not the length of
the block (DecodedBkpBlock.bimg_len).

Oversight in 57aa5b2bb11a, probably due to some copy-paste from the
surroundings.
