EDIT: This approach can be extended to get the list of tables dynamically by running a query through psql and feeding the results into the loop instead of a hard-coded list:
for table in $(psql -U userName -d dbName -t -c "Select table_name From information_schema.tables Where table_type='BASE TABLE' and table_name like 'thr_%'");
do pg_dump -t $table -U userName dbName > /home/anik/psqlTest/db_dump_dir/$table.sql;
done;
