Can you please install extension pageinspect, then grab the TIDs of both
copies (select ctid from srmlinkgroup where id = ..), then post the
output of:
select *
from heap_page_items(get_raw_page('srmlinkgroup', BLKNO))
where lp = (OFFNO)
where the BLKNO value is the first half of the TID, and OFFNO is the
second half of the TID, for each of those tuples?
Please attach the results in text files rather than pasting in the
email, as whitespace is mangled by your mail program.
Thanks
