Re: Need to change the size of a field

suresh

This is pretty simple.... Just do a pg_dump of the of the database,
edit the text file, and reimport the new definitions.

something like

dg_dump 'targetdb' > outputfile

This is the same thing you are doing to backup your data. : )

Next open the outputfile in a text editor. Notice that you have all the
create table directives. Edit the value in the definition area and save
the file.

drop the original database. then reimport the dump file (you will first
have to createdb because you dropped it remember).

That's it. Your pg_dump files are your friends.
