No, we have not implemented that. You can add a column, copy the data over from the old column, then drop the old column and rename the new column. --------------------------------------------------------------------------- =?iso-8859-1?Q?frank=5Flupo?= wrote: > Is possible to alter table change type of column? > > > Bye !! > Frank Lupo (Wolf) !! > > /\_ _/\ > \ o o / > --ooo-----ooo--- > > > > -- > Prendi GRATIS l'email universale che... risparmia: http://www.email.it/f > > Sponsor: > Conto Arancio, il migliore amico dei tuoi risparmi. > Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=668&d=24-3 > > > ---------------------------(end of broadcast)--------------------------- > TIP 6: Have you searched our list archives? > > http://archives.postgresql.org > -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

BTW, do the functions and indexes automatically get dropped if they are referencing a column that gets dropped?

Uh, indexes get dropped, I think. I am not sure about functions --- I don't think so because we don't always know what columns are referenced in a function. --------------------------------------------------------------------------- Dennis Gearon wrote: > BTW, do the functions and indexes automatically get dropped if they are > referencing a column that gets dropped? > > Bruce Momjian wrote: > > Yes, afraid so. > > > > --------------------------------------------------------------------------- > > > > Dennis Gearon wrote: > > > >>And then redo all the triggers and indexes also? > >> > >>Bruce Momjian wrote: > >> > >>>No, we have not implemented that.
