1) Create the directory %APPDATA%\postgresql
in my case it's C:\Documents and
Settings\Administrator\Application Data\postgresql
2) Create the file %APPDATA%\postgresql\pgpass.conf
I created it with Notepad
3) Put the necessary information into %APPDATA%\postgresql\pgpass.conf
I put one line in mine -
localhost:*:myDBname:myUserName:myPassword
4) Create the batch file to run your backup command
In my case, it reads:
"C:\Program Files\PostgreSQL\8.0\bin\psql" -h localhost -d myDBname -U
myUserName -f Name-Of-File-With-Maintenance-Commands
"C:\Program Files\PostgreSQL\8.0\bin\pg_dump" -f Name-Of-My-Dump-File
-Fc -Z 9 -h localhost -U myUserName myDBname
5) Use the task scheduler to run your newly created batch file whenever
you'd like it to run
I actually run my batch file every night. My DB has no activity during
the night, so I run my maintenance then.
Name-Of-File-With-Maintenance-Commands contains SQL to refresh a
materialized view and do a vacuum full analyze

Use a pgpass.conf file:
http://www.postgresql.org/docs/8.0/static/libpq-pgpass.html (remember
the file has to be in the profile of the account that executes the step.
And be sure to protect it with file system ACLs so other users can't
read it)

Perhaps its like this. pg_dumpall wants to dump the whole database-cluster (every database in your server) that is not only "MONITORINGZ" but the two templates, too. So pg_dumpall doesn't ask you for the password to your own database but 2 times for the pw for the 2 template DBs. In pgpass.conf write * instead of MONITORINGZ or copy the line for template0 and template1. Or don't use pg_dumpall and use pg_dump instead just for MONITORINGZ. Maybe it's somerthing else ... one never knows with those computers ... ;)

Hi all,
I stop the following statement after 3 minutes....
explain analyse select *
From IC
where IC.ICNUM NOT IN (select IRICNUM from IR WHERE IRSTATUT in
(1, 2))
I'm using 8.0.3 on windows.
Is that a know bug ?
Thanks
/David
P.S.: I can send more info if needed.

David, Remember that EXPLAIN ANALYZE actually RUNS the query. It may actually be taking 3+ minutes to run the query. How large are the tables? What does EXPLAIN (without ANALYZE) say? Have you run the query without EXPLAIN ANALYZE to know how long it normally takes--what is the basis for suggesting that 3 minutes is "too long"? Sean

Post your schema, and the sizes of the tables in question. Also, a regular EXPLAIN (without ANALYZE) should print the query plan that PG has chosen--post that too. -Doug
