Re: Timing a query

This is fantastic patch.

Thank you very much.

(For "rookies" (such as myself), to apply the patch you will need "patch",
which is not included in the boxed RedHat 7.1 distribution. I got
patch-2.5.4-9.i386.rpm from ftp.rpmfind.net.)

I'll assume you have the sources for 7.1.3. I'll rewrite the
patch for 7.2b3 in a little bit.

Change to the top level of the postgresql source tree.

> cd postgresql-7.1.3

Save the file at
http://www.gtsm.com/postgres/microtiming.patch
to a local file, perhaps named "microtiming.patch"

> wget http://www.gtsm.com/postgres/microtiming.patch

Patch the source with the file:

> patch -bp0 < microtiming.patch

If all goes well, you should see:

patching file ./src/bin/psql/command.c
patching file ./src/bin/psql/common.c
patching file ./src/bin/psql/help.c
patching file ./src/bin/psql/print.h
patching file ./src/bin/psql/startup.c
patching file ./src/bin/psql/tab-complete.c
patching file ./doc/src/sgml/ref/psql-ref.sgml

You can then run make from the top-level directory, or
to avoid some output, cd to src/bin/psql and run
make from there:

>cd src/bin/psql; make

When finished, you'll have a new psql binary in the
src/bin/psql directory, which should have the microtiming
stuff. Test it out before copying it over to anywhere
permanent:

>./psql

template1=# select version();
                           version

 PostgreSQL 7.1.3 on i686-pc-linux-gnu, compiled by GCC 3.0.1 (1 row)

template1=# \m
Microsecond timing is on.
template1=# select version();
                           version
- - --------------------------------------------------------------
