Hello,
        Here's a quick function to count the total number of rows in none
system tables:
DROP FUNCTION cnt_rows();
CREATE FUNCTION cnt_rows() RETURNS int4 AS '
DECLARE
        r RECORD;
        rb RECORD;
        tot int4;
        sqlstr text;
BEGIN
        tot:=0;
        FOR r IN select * from pg_tables where not tablename like ''pg_%''
LOOP
                sqlstr:=''SELECT count(*) AS cnt FROM '' ||
quote_ident(r.tablename) || '';'';
                FOR rb IN EXECUTE sqlstr LOOP
                        RAISE NOTICE ''Number of rows in
%=%'',r.tablename,rb.cnt;
                        tot:=tot+rb.cnt;
                END LOOP;
        END LOOP;
        RAISE NOTICE ''Total Number of rows for all none system
tables=%'',tot;
        RETURN tot;
END;
' LANGUAGE 'plpgsql';

You'll also need to have the plpgsql language created for your database
(eg: createlang plpgsql testdb)
then just execute the above script then select cnt_rows(); in psql.

the need is to get TOTAL RECORDS of all the THREE DATABASES or atleast

Seems to be simple.
Thankx in advance and infact i was a newbie.
