Ready For Committer patches (CF 2020-11)

Hi,

with this message, I want to draw attention to the RFC patches on the
current commitfest. It would be good if committers could take a look at
them.

While doing a sweep through the CF, I have kicked a couple of entries
back to Waiting on author, so now the list is correct. Now we have 17
entries.

https://commitfest.postgresql.org/30/?status=3

The oldest RFC patches are listed below. These entries are quite large
and complex. Still they got a good amount of reviews and it looks like
after a long discussion they are in a good shape.

Generic type subscripting <https://commitfest.postgresql.org/30/1062/>

schema variables, LET command <https://commitfest.postgresql.org/30/1608/>

pgbench - add pseudo-random permutation function
<https://commitfest.postgresql.org/30/2138/>
Allow REINDEX, CLUSTER and VACUUM FULL to rebuild on new
TABLESPACE/INDEX_TABLESPACE <https://commitfest.postgresql.org/30/2269/>

range_agg / multiranges <https://commitfest.postgresql.org/30/2112/>
