Subject: Disk space consumption: character varying(255) versus text used for index

Hi,

my btree index for

   guid                | character varying(255)

is currently 6.9GB (almost all guid entries are of size 37bytes)

If I would change the data type to

  guid                | text

would the index size be reduced (without hitting performance)?

thank you
Marcel
