Me, too. I forgot to ask for the table definition. If there are
variable-length fields like "text" or "varchar", what is the typical
size of the data.

Also, what is the physical size of the table (\dt+ yourtable)?

Perhaps even the output of
select * from pg_stat_user_tables where relname='yourtable';
might be useful.

Cheers,
Steve
