It's good to see commands for a concurrent reindex scripted.
For rendering tables I'd recommend pausing updates, creating a new
ordered table, building indexes on the new table, then putting the new
table in place. The reclustering adds performance beyond what a reindex
does.
http://paulnorman.ca/blog/2016/06/improving-speed-with-reclustering/ has
example SQL.
For slim tables, I'd probably just pause updates and REINDEX.
http://reorg.github.io/pg_repack/ would be interesting on the slim
tables but can't operate on the rendering tables.
