Subject GUID/Random number generation?
Author randallsell

I have a requirement to create a unique 7 character string (numbers
and letters). In the file-based implementation, we simply extracted
the first 7 characters of a GUID. But I see no way to obtain a GUID in
PSQL. Surely there is a RANDOM function? But didn't find a reference
to such a beast in Helen's Bible.

BTW- I can't used a Generator because these values are not internal.

So, is there a free library I can obtain to either generate a GUID or
a random value?
