How to create a postgres column with a default timestamp value of epoch?

Question

I want to create a timestamp column with a default value of epoch. How can I do it? This, and all the variations I've tried don't work:

...
last_viewed_at     TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT TIMESTAMP "epoch",
...

Answer 1

It's all about double quotes vs single quotes. Double quotes are for identifiers so you want:

...
last_viewed_at     TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT TIMESTAMP 'epoch',
...
