Re: pgdump and restore results in different sizes DB

Get approximate counts the shortcut way:
Do analyze on all your user tables. Then, do a join with pg_namespace, pg_table(s), and pg_class and spit out the scheme, table name, and number of rows(reltuples).

Not near a computer so forgot if it is pg_table or pg_table.
