If i got it correct, CLUSTER would do the same what VACUUM FULL does (except being fast).
CLUSTER is recommended only because it is faster ? As per the link, the table would be unavailable (for shorter period compared to VACUUM FULL) when CLUSTER is executed as well. Hope i got it correct !
Thanks

I as a DBA, suggested to perform VACUUM FULL and RE-INDEXING + ANALYZE to ensure that IO performance and Indexing performance would be good
