Description:        I NEED HELP
Details:

I USE POSTGRES AND I AM A LAYMAN.  I HAVE TRIED LOOKING EVERYWHERE TO FIX MY
ISSUE BUT EVERYTHING LOOKS LIKE FOREIGN LANGUAGE TO ME.  I CAN'T FIGURE OUT
HOW TO FIX MY PROBLEM.

I USE A PARTICULAR SOFTWARE TO ACCESS A DATABASE.  MYSTERIOUSLY, MY
SOFTWARE'S DATABASE MANAGER SHOWS 2 DATABASES.  ONE OF THEM IS THE ONE I
CREATED.  THE OTHER IS CALLED "INSTESTDB" AND I'VE NEVER SEEN IT BEFORE.  I
AM SCARED SOMEONE HAS HACKED INTO MY COMPUTER.

PLEASE HELP!!! I AM GOING CRAZY TRYING TO DELETE THAT DATABASE AND MAKE SURE
EVERYTHING IS OK.

THANK YOU-DAN BALDEV
