you can do this:
select reltuples from pg_class where relname = 'your_table' and relkind = 'r';
that will give you accurate count as of the last analyze, which is
going to be driven by table usage and/or manual analyze. Probably
much better in your particular case is to do this:
select * from pg_stat_all_tables where relname = 'your_table';
and look at the n_tup_ins, del, etc. and make sure they are changing
(those numbers are reset when server resets, fyi).
