Could we plan a more comprehensive survey, with more than one question?
Judging by the number of people who fill out surveys, we would still get

Dear all,
I completed my Computer Science MSc thesis in Athens University of Economics

subject was DAIMON: Data Integration for a Mobile Network, i.e. mobile
peers integrating data from other peers. We used PostgreSQL
wht i wanted to do is... identify the tables which are getting used simultaneously... so that i can move them to different tablespaces
for that i tried to do sampling of "pg_statio_user_tables" for top 20 tables...(in terms of usage)... so that i know how much io is being done... for

Dear people,
Does anyone know how to execute an OS command from pgsql. I
would like to create a trigger that op on firing would run/execute an external

Does such functionality exist or do I have to write my own trigger
function in C.

Gevik.

Is there a good source of multi-byte copy data test cases? What is
currently done to test the trans-coding support? (where client and server
encodings are different)
I notice that the regression data in the CVS version of postgres does not

We have two and three-byte encodings, so 16-bit seems like it wouldn't
work. I am not aware of any specs except the C code itself.
Ok - no problem.
How about test data and cases? I see the SQL encoding examples used in
src/test/regress/sql for testing encoding in SQL, but are there

I have no idea what you are talking about. Again, give me facts about
what we currently don't do and what you want to do.
Currently:
