You can try pgcompact from PgToolkit [1]
pgcompact -d dbname -t tablename -r -v info
that will concurrently reindex those indexes that are bloated and will
remove bloat from the table without recreating it in the case if it is
bloated only. It might require pgstattuple extension [2] to be
installed [3] .
