Try:

select pg_stat_get_last_vacuum_time(oid) from "pg_catalog".pg_class where relname = 'tablename';

select pg_stat_get_last_autovacuum_time(oid) from "pg_catalog".pg_class where relname = 'tablename';

On this old release, the only way you can find such an information is
via the logfile and using DEBUG1 or DEBUG2 level. Not something I would
recommend for a production server.
