B> thank you for this tip!  don't know what the ^ or the $ is used for

regular expression operators ^ stand for first character and $ stand
for last character:

    ~* '^india$'

matches  India
         india
         INDIA
         
but not  Indiana
         New India

Take a look at PostgreSQL User's Guide, Chapter 5, there's some
information about PostgreSQL operators.
