Hi,
Im v.new to postgres. I needed some help writing batch files.
I wanted to run psql commands in a batch file.
I give 2 inputs to the batch file -- Username and Database name
I want my batch file to do the following things.

- check if a database created by that user exists if true return 1 else return 0

Anyone who knows how to do this , please help !

I'm not sure if you work under linux or windows. This is linux script that meets you requirements

#!/bin/bash
psql -t -c "select * from pg_user u,pg_database d where u.usesysid=d.datdba and usename='$1' and datname='$2'" > myfile
z=`wc -l myfile | cut -d" " -f 1`;
if [ $z -le 1 ]
then echo "0";
else
        echo "1";
fi
rm myfile

i guess it is not perfect but i didn;t write a scipt for a long time :).
