pg_stat_get_backend_activity() is an internal function, so in order to see how
it works you must look .../src/backend/utils/adt/pgstatfuncs.c

However, the system can give only active queries, if you need recent queries
then you should enable
log_statement = true
in postgresql.conf and
kill -HUP <postmaster_pid>
where postmaster_pid is
tail -1 ~postgres/data/postmaster.pid
