Lack of new posts
Sorry for delay in writing new posts – especially new information about “what's new in pg 8.4".
I've been on vacation, and crashed my car. New posts will be coming this week – for starters – I have 244 unread mails from pg-committers mailing list, so you can expect at least couple of new things in 8.4 🙂
Suppressing CONTEXT lines in psql
CONTEXT messages are quite informative, but when you don't need them, they can be real pain in the eyes:
psql:trees.sql:68: NOTICE: Adding tree structures to table public.testit. CONTEXT: SQL function "add_tree_structure" statement 1 psql:trees.sql:68: NOTICE: Tree table will be public.testit_tree. CONTEXT: SQL function "add_tree_structure" statement 1 psql:trees.sql:68: NOTICE: Primary key in source table is: id CONTEXT: SQL function "add_tree_structure" statement 1
I mean – I know the context. I'm writing the sql file right now, how to disable it?
Who/what is trashing db performance?
Every so often I need to find who exactly is damaging database performance. I mean – I have db connection which does something strange/wrong with the database, but what exactly is responsible?
Switching to separate user for every program, script and developer would solve the problem, but it is not always an option. So, what should I do?
Conditional DDL?
Every now and then I see people ask the question – how to create table if it doesn't exist yet, how to drop it, but only if it does exist and so on.
Well, starting from 8.2 dropping should be not a problem anymore. But what about create? Alter?
Let's try to do it…
