I have the following function in PostgreSQL 7.2.1 on i586-pc-linux-gnu, compiled by GCC 2.96:
CREATE FUNCTION "fct_vacuum_db"() RETURNS "int2" AS '
DECLARE
db_table RECORD;
v_overhead float;
BEGIN
FOR db_table IN SELECT relname FROM pg_class WHERE relname like ''tb_%'' AND relkind = ''r'' LOOP
SELECT pgstattuple(db_table.relname)INTO v_overhead;
IF v_overhead >= 0 THEN
RAISE NOTICE ''Vacuuming table (%)'',db_table.relname;
EXECUTE ''vacuum analyze ''|| db_table.relname || '';'';
END IF;
END LOOP;
return 1;
==============================
Using the function pgstatuple I want to use this to control what gets vacuumed. However, whenever the EXECUTE statement
runsI get the following message from the backend:
==============================
NOTICE: physical length: 0.00MB live tuples: 0 (0.00MB, 0.00%) dead tuples: 0 (0.00MB, 0.00%) free/reusable space:
0.00MB(0.00%) overhead: 0.00%
NOTICE: Vacuuming table (tb_a)
server closed the connection unexpectedly This probably means the server terminated abnormally before or while
processingthe request.
The connection to the server was lost. Attempting reset: Failed.
===============================
What am I doing wrong ??
