[GENERAL] change column data type from smallint to integer
Hello, we run 'out of space' in one of our columns which is smallint and we need to make it integer. I did some research and found out that the only way is to create a new column with integer data type, then SET new = old, then drop old and rename new like old [1]. Could somebody confirm if this is really the best way and if it is stable in respect to indexes, RI, triggers, stored procedures, etc. Thank you, Iv [1] http://www.foranewliberty.com/blog/archives/2005/01/15/changing-data-types-in-postgresql/ ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster

In releases before 8.0, you have found the right workaround. -- Alvaro Herrera -- Valdivia, Chile Architect, www.EnterpriseDB.com "Crear es tan difícil como ser libre" (Elsa Triolet) ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings
