One more thing. If the value is the empty string, then in the View Data shows it as ''

Hi guys,
A bit more info.
If I write a query manually (i.e. SELECT * FROM table) then the column shows up as "<NULL>" which is what I expect.
However, if I write click the table and hit the "View Data" menu option, the column is blank.

Another slight bug (I think):
I have a table which has a column called "first_invalid" which should be a timestamp if the record is invalid, or NULL if it's valid.
In PgAdmin I have the "Show NULL values as <NULL>" option enabled, but it still displays a blank cell for this column.
The reason why I think it may not be a bug, is I tried doing this:
"SELECT COALESCE(first_invalid, '<NULL>') AS first_invalid FROM table"
but PostgreSQL threw it out because "<NULL>" is not a valid timestamp - instead I had to do:
"SELECT COALESCE(first_invalid, '1900-01-01') AS first_invalid FROM table"
to prove the column is in fact NULL, and I do get: "1900-01-01 00:00:00+00" for this record, but in the data entry grid, PgAdmin still displays it blank.
Question: is this a bug, or intended behaviour?
Thanks,
Andy
