I'd like to find the epoch time at which a certain row was loaded, so that I can pick out appropriate table decorators for fetching other events loaded in close proximity. How can I query this data?
AFAIK there is no automatically created column that holds the row time of creation - but you could certainly add one while loading data.

I have a view called 'selectView' in my postgresql database.
How i can get the results in to my server.js(nodejs code) like,
select * from selectView
Please suggest.
Sorry for the earlier mis-understanding. Didn't know node.js was server-side. A little search engine (you know the one) tells me that there's a postgresql library available for node.js. That should help you out.

Qt Quick Controls:
The Calendar control was added. Calendar allows selection of dates from a grid of days, similar to QCalendarWidget.

I have the following URL in a table and I am given the responsibility to develop a script to remove the dots around the date.
For example:
The Date: 2013.01.20 should be read like the following in the url:
http://local.website.net/doc/q?file=5448245&date=20130829&ref=65457
Note the dots for http://local.website.net should not be removed.
How I can get started on this?
DECLARE #doc varchar(500) = 'http://local.website.net/doc/q?file=5448245&date=2013.08.29&ref=65457'
SELECT SUBSTRING(#doc,0,CHARINDEX('date=',#doc))+REPLACE(SUBSTRING(#doc,CHARINDEX('date=',#doc),LEN(#doc)),'.','')
