Help needed in testing my code.
Dear Sir,
I want to know the compilaiton and execution of my
code. Suppose if i add a test printf statement in the
src/backend/tcop/postgres.c and after compilation and
execution i should get that statement every time i give
a query to psql.
After running make I even added the executables
in the /usr/bin/ directory but i couldn't see the test
statement after giving a query to psql.
please tell me the procedure of adding a test
printf statement in postgres.c(or in any file), and
compiling and running it so that i get the test statement
as an output when i give the query.
Sincerely
Srikanth M
Why don't you use elog(LOG, instead of printf ?

Hi,
This is a much better way than printf:
elog(NOTICE, "this is my test: %s", string);

TIP 5: Have you checked our extensive FAQ?
I'm guessing his problem is that he's expecting this to come out of psql
and not go to the backend's stdout.

As you're a big fan of stealing code, why don't you grep the source
for occurences of "elog(LOG" or "elog(NOTICE".
elog(NOTICE should send NOTICE messages to the psql client (I think !)
while elog(LOG while only send it to the logfile you might have
specified while starting the postmaster

Well you sould start out by RTFM .. read how to build postgres. I run
"make install" in my postgres directory (right above src/).

Is anyone working on, or planning on working on the describe statement?
It is very useful for ecpg, and a project I am working on.
Depending on the amount, I may be able to get compensation for this, if
this helps motivate anyone?

Whether a given elog level is sent to the postmaster log and to the
client, is controlled by client_min_messages and server_min_messages.
At least in recent sources, that is.
