Hi all,
In brin_doupdate(line 290), REGBUF_STANDARD is used to register
revmap buffer reference in WAL record. But, revmap buffer page doesn't
have a standard page layout and it doesn't update pd_upper and
pd_lower as well.
Either we should register revmapbuf as following:
XLogRegisterBuffer(1, revmapbuf, 0);
Or, we can update the pd_upper and pd_lower in brin_page_init() as follows:
if (BRIN_IS_REVMAP_PAGE(page))
p->pd_lower = p->upper.
To fix this, I've attached a small patch which follows the first approach.
