In the middle of putting out a proposal for a very large client/tender at the moment. Well over a life time’s earnings in servers and an as yet un calculated retainer and service rate at this stage – electricity and bandwidth and human hours all cost money.
I always try to get the best prices [...]

Ever had a situation like this:
Select from database ID where name = RICHARD;
Returns and ID of 55 for example.
Then go and do a query like this:
Select * from some_other_table where ID = 55;
Returns, “Sorry does not exist, time to die…..”
Well apparently indexes when corrupt – which is NOT SUPPOSED TO HAPPEN – can cause PostgreSQL [...]

During a recent test run to see if a new PostgreSQL back end server would hasten things up in a main cluster – that has now become CPU bound and NOT IO…… the wizardry of that I will blog about later.
In any case, the short of it is, that we were juggling PERC4 cards around [...]

Excellent Results!
CPU
System load was DOWN. This is due to much better disk IO (reduced wait times) and as such, user processes get to breath and send stuff back to clients in a speedy fashion.

I knew the config files were different between 7.4 and 8.1 and that some items merely changed names and some were deprecated.
I used this excellent resource before.
Even the very rudimentary tweaks I did, and with a RAID array that is in a 90% rebuild rate, background initialisation, this 8.1 version is FAST! I have [...]

Well, the PostgreSQL upgrade was a snap, sorta. I needed to do a full dump and restore as this was a major version change – no surprises there. What pissed me off though, is that when using the binary data type for dump files when using pg_dump (“-T c”) the resulting backup file [...]
