A bit more information is required. What version of Postgres are you using, what
OS? I am guessing that the compressed string is being created by a Python
program external to the database and then inserted into a field, is this
correct? You are then trying to decompress the string via a plpythonu function
within the database,correct? Did you import the zlib module into the plpythonu
function?
