@nagar16730416

The question was also asked before, with some suggestions given in Reading BLOB data from pzPVStream column with Java

there is a good discussion Understanding Pega Blob and UDF and CustomerData (non-blob) vs PegaDATA (blob)

The same Pega employee also answered the question in How to read pzPVStream (BLOB) in PostgreSQL
