Re: Selects query stats?

[Dan Gorman <dgorman@xxxxxxx>]

In any other DB (oracle, mysql) I know how many queries (selects) per second the database is executing. How do I get this 

number out of postgres?

I have a perl script that can test this, but no way the db tells me how fast it's going.

(e.g. in oracle: select sum(executions) from v$sqlarea;)

Regards,

What I am looking for is that our DB is doing X selects a min.

What specifically would you like to measure?

Duration for specific queries?

Queries in an app for which you have no source?

There may be a way to get what you want by other means ...

Details?

I gather you cannot just time the app that's doing the selects,

nor extract those selects and run them via psql and time them

on their own?

All,

I might be completely crazy here, but it seems every other database exposes select query stats. Postgres only exposes updates/deletes/inserts. Is there something I am missing here?
