Re: change existing table definition

Hi

ALTER TABLE is only in PostgreSQL 8. But you can create a new table
with varchar(50) and copy the data from the existing into the new
table. How much relation_size has your table? Do you create the
dbsize-functions which are included in the contrib package?

Best regards,
Martin
