Thread: Returning bytea* from a C function

List,
    I'm trying to build a function for PostgreSQL that allows me to create a
new UUID for data in my datbase.  Has anyone had experience with this
one?  I was going to store it as a bytea datatype, would a char(32) be
better?  Any Ideas?

If your table will be very large, using bytea will save a fair amount of
space. Other possibilities are to encode the data into base64 or hex and
store in a TEXT (or VARCHAR or CHAR()) field.
