Re: how can we get total records in pg server?

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.
