Maybe to show how "found" works and how to ignore errors - that is my

I am going to start with quotation: "*PostgreSQL is a powerful, open

Hi,
instead of
*update workorderRecord set wfstatus='failed'; *
try:
workorderRecord.wfstatus := 'failed';
I haven't tested, but workorderRecord is ROWTYPE, so shouldn't be updated
like a table.
I'm sticked to 9.1, hope the same is for 8.1

Hi,
there shouldn't be any problem in installing extensions to multiple
databases in the same server. Extensions are per database:
http://www.postgresql.org/docs/9.1/static/sql-createextension.html
You can use pgAdmin, or try this syntax:
CREATE EXTENSION hstore
SCHEMA public
VERSION "1.0";
Hi,
You can use one of windowing function:

this could be rank() in subquery or first_value(vale any), but there could
be performance issue
another solution could be boolea

Hi,
what about this:
SELECT p.rolname, m.rolname as member, g.rolname as grantor
FROM pg_authid p
INNER JOIN pg_auth_members am ON (p.oid = am.roleid)
INNER JOIN pg_authid m ON (am.member = m.oid)
INNER JOIN pg_authid g ON (am.grantor = g.oid)
You can use proper WHERE to filter results.

I think You can use epoch

One more thing:
TRUNCATE has option CASCASE:
http://www.postgresql.org/docs/9.1/static/sql-truncate.html
I don't remember since when, but 9.X has this option.
Another thing: Do You really need this function.
AFAIK since 8.4 postgres has TRUNCATE privilage on Table

Hi,
how about inheritance in postgres?

(
id serial NOT NULL, -- serial type is my assumption.

);

Hi,
according to DB theory:
*1NF: Table faithfully represents a relation and has no repeating groups*
*2NF: No non-prime attribute in the table is functionally dependent on a proper

dimensional space - axis: col1, date (line between points X, Y1
hi,
my suggestion is to redesign reporting database to fit reporting specifics
(e.g. brake normal form of database, in some cases this will speed up
reports). Than you can use some ETL tool to sync production and reporting.
Good thing is to use some OLAP software to use multidimensional analyze -

I know what unlimited means, but I suggest to change docs to be more
accurate.
Those "limits" are huge (e.g. number of indexes limited by pg_class table
size), but still exists.

Hi,
thanks, this will help me :)
Maybe one small hint:
You use only table name variable (p_table_name) which I assume should
contain schema name. If so then quote_ident ('aaA.bbbB') will give You
"aaA.bbbB" but not "aaA"."bbbB". This will produce error. It is better
idea, in my oppinion, to add p_
