BUG #4166: Alter table add column from PgAdminIII

Mike Gagnon wrote:

I used PGAdmin III to add a character varying column(400) length, not null
default ''. I get the column displayed in psql when I do a simple query
like SELECT * from MyTable limit 1;

When I try to do Update MyTable set NewColumn='something'; I get the error
saying that the column doesn't exist.... It thinks it exists when I do my
select, but it doesn't recognize this new column in my UPDATE...

Perhaps you created the column with a capital letter? If that's the
case, you'll have to quote the column name: ... set
"NewColumn"='something'. If that's what happened, I'd suggest dropping
and recreating the column in all-lowercase.

If this didn't help, please post the output of the "SELECT *" verbatim.

I'm betting you have a case sensitivity problem. Either you created the
column as "NewColumn" with quotes and are trying to reference it without
quotes, or vice versa.
