Value too long varchar(275) error with src/AdminViews/v_generate_tbl_ddl.sql about amazon-redshift-utils

Have you tried with other values ( like 1024 instead of 8000 ) ?

8000 is semi-arbitrary. The size just has to be large enough to hold the text of a long FOREIGN KEY object name. 1024 would work until you had a DDL generation for a line needing 1025 characters.

Correct. Given the max size of objects( tables and columns ) 1024 should be enough.
8000 has performance implications. If 1024 works for you, I will go with that for now.

Pushed fix

Looks like the problem isn't fixed. The fix should go on line 89 in the --CONSTRAINT LIST section of the query. This can be reproduced by adding a UNIQUE constraint on a table using enough columns to blow past 275 characters, and then querying v_generate_tbl_ddl. The fix is still the same as I described - change line 89 to:
,'\t,' + pg_get_constraintdef(con.oid)::VARCHAR(1024) AS ddl
