So, Dan, the question is, what are you trying to measure?
This might be a statistic that management has always been given,
for Oracle, and you need to produce the "same" number for PostgreSQL.
If not, it's hard to figure out what a

If you're using 7.4, you can use log_duration to only log duration. It
won't log all the query text, only one short line per query. Then you
can use pgFouine to analyze this and havi

Yeah, the problem seems underspecified. How do you count statements

Yeah, I'm not really concerned about the app or sys performance, just
a basic question of how do I get the rate of selects that are being
executed.
In a previous post from Jim, he noted it cannot be done. I am very
surprised postgres can't do this basic functionality. Does anyone
know if

You can't. You also can't know how many DML statements were executed
(though you can
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,Da

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 j
What I am looking for is that our DB is doing X selects a min.
Turning on logging isn't an option as it will create too much IO in
our enviornment.

You can EXPLAIN ANALYZE a SELECT, just like i/u/d -- but then you
