There is no GUI tool that I know of, but there is EXPLAIN which gives
the same information.

Hi,
You can do this with Postgresql by turning on log statements in the
postgresql.conf file.
You can then trace all the statements that the server executed in the
log and the values that where passed.

You could also check out Lightning Admin instead of pgAdmin III.
We have a feature that can capture the currently running statement from
a process and list them all in a memo.
Can be handy.
You can find out more here:

While not free, Lightning Admin is SUPER inexpensive :-) and you will
get great support.

I thought that was called SQL Profiler.

http://msdn2.microsoft.com/en-us/library/ms181091.aspx

Query Analyzer is EXPLAIN with a GUI.

http://msdn2.microsoft.com/en-gb/library/aa178423(SQL.80).aspx

Anyway, I have not heard of such a thing for PostgreSQL, although I am
sure the basic information you want could be obtained from logging
queries and timing.

The SQL Profiler tool also keeps data that meet your criteria for
later analysis as well.  It is very good.

Ian,

On my installation of PostgreSQL from the stock windows installer
there was installed PgAdmin, which has quite a GUI for EXPLAIN.

The query plan is displayed very nice and I find it easier to
understand then text output.

that is within Tools / View Server Status of pgAdmin III

Of course, Query Command String has to be enabled on the server; and
the security implications of that setting have to be considered before
:)

best wishes,

Hi,
I may be wrong but:
Enabling query logging (in the options dialog) will only log the SQL
pgAdmin III sends to the server, it will not capture the query for a
selected process
in the server status dialog.
If you want something like the trace in MS SQL server Lightning Admin
has something similar:
http://www.amsoftwaredesign.com/onlinehelp/pgla/server_status.htm
You can select the process ID you want, then check the Capture selected
rows query option and all the queries for that process that become
visible will be
logged to a memo control, you can then copy the captured queries to
where ever you like.


Later,

Out of curiosity, how does that work? I mean, how does it pick up when a
new query has been issued? Do you use some server-proc to tail the
logfile or such?
