Hello Keith,
Thanks for this script and for reminding about pgstattuple.
The script has the drawback of requiring r/w access to the database, so
it cannot be run on a replica. But the idea is excellent. At least it
can show the top N bloated relations, and then I can further explore with
pgstattuple(), pgstatindex() etc.
