The examples come with the psycopg distribution.
If you have not downloaded that and looked through
it and read the instructions included with it, I am not
quite sure why you are asking here first.

Well. That seems like the first step. Maybe there are
pre-built packages available for your operating system.

Your code previously worked just fine to get the input
from the user through the web. Just instead of asking
for a complete SQL query (which would be a bad idea)
Just ask for keywords and build up a string from there.
You need to learn things one step at a time. If you do
not yet know how to create a string from other strings
you need to learn that first.
By the way. The code I posted yesterday was bogus...
some kind of bad mix between your code and my code.
This works w/ psycopg:
# Now, we can get to the database...
db = psycopg.connect("dbname=test user=%s"%username)
cursor = db.cursor()
listOfResults = cursor.dictfetchall()
Sorry about that.
