Re: Change size of a field

Hi,

Thank you, it works but I loose my foreign keys and the privileges for
groups and users. 

Is there a solution ?

Pretty normal!
just 
1) % pg_dump -t <tablename> <dbname> > <tablename>-DUMP.sql
2) % psql  # drop sequence <tablename>_id_seq;
3) vi <tablename>-DUMP.sql  change your varchar(50) to varchar(80)
4) psql  #\i <tablename>-DUMP.sql

There you go
