In your case you must use 'large > objects' as datatype for big text. How does one do this, preferably with perl and DBI? What is the best way to handle big (>= 8k) text fields? It would be nice if postgres could have an easy interface for larger text sizes or a set of example functions to deal with such chunks. A connected question of mine is: I have played with the data types text and varchar to store some text from a webbrowser with a perl-DBI cgi script. The table has one INT field called "id" and one text field where I tested the types: text, varchar, varchar(2000) and varchar(7000). Inserting text only works if the text is a lot smaller than 8k - only about 20 lines of text get inserted without beeing cropped. How can I assert that the whole text gets inserted and how can I get a message/error if the text did not fit or has been shortend? Has anybody an example script or perl code snippet with text fields roughly 2000-4000 bytes long? This problem annoys me for some weeks now so I think I am an idiot and Postgres proves it... Any help would be great and maybe let me sleep better ;) -- __ __ Frank Barknecht ____ ______ ____ __ trip\ \ / /wire ______ / __// __ /__/ __// // __ \ \/ / __ \\ ___\ / / / ____/ / / / // ____// /\ \\ ___\\____ \ /_/ /_____/ /_/ /_//_____// / \ \\_____\\_____\ /_/ \_\
