Hi Jesper,
Some initial comments.
_hash_vacuum_one_page:
+ END_CRIT_SECTION();
+ _hash_chgbufaccess(rel, metabuf, HASH_READ, HASH_NOLOCK);
The _hash_chgbufaccess() needs a comment.
You also need a place where you call pfree for so->killedItems - maybe in
hashkillitems().
Thanks for reviewing this patch. I would like to update you that this
patch has got dependency on a patch for concurrent hash index and WAL
log in hash index. So, till these two patches for hash index are not
stable I won't be able to share you a next version of patch for
supporting microvacuum in hash index.
This can be rebased on the WAL v7 patch [1]. In addition to the previous
comments you need to take commit 7819ba into account.
