Table Editor doesn't allow default values like `CURRENT_DATE`

Bug report

Describe the bug

The Table Editor in Studio doesn’t allow default values like CURRENT_DATE. However, it works as expected when done via SQL (both creating and altering a table).

To Reproduce

1. Create a new table:

CREATE TABLE testdate (
    id BIGINT GENERATED ALWAYS AS IDENTITY PRIMARY KEY,
    date DATE NOT NULL
);

1. Go to Table Editor and add default value CURRENT_DATE to column date.

This results in the notification: Failed to update column “date”: failed to update pg.columns with the given ID: invalid input syntax for type date: “CURRENT_DATE”

Expected behavior

When using SQL directly, you can set the default value and it works as expected:

ALTER TABLE testdate ALTER COLUMN date SET DEFAULT CURRENT_DATE;

I expect that the Table Editor supports values like CURRENT_DATE. (I have not tested CURRENT_TIME and similar, but expect the same behavior)

This is one of the cases where defaultValueFormat needs to be "expression" I think - otherwise "CURRENT_DATE" will be treated (and escaped) as a string literal.

[joshenlim]

basically treat it as expression

hmm but this wouldn’t be right on the UI. esp if a user saved their default value as a literal, and they open the editor again and it shows that Is a SQL expression is toggled true
