I have a field called postTimestamp.

The trigger function could not reference it.

When I change my field to post_timestamp. I can reference it from the tigger function.

Version is 9.3.5. Any comment?

field and talbe names with mixed case have to be "Quoted".      string constants, on the other hand, are are in single 'quotes'.

try...

SELECT * from tbl1 where new."postTimestamp' > timestamp '2014-01-01 00:00:00'

those two error logs have different timestamps, I don't believe that error is on that statement.

there's a whole lot of unnecessary typecasting in that insert, however.

INSERT INTO public.tbl1("vendor", url, "postTimestamp", product, "type", "itemID")
    VALUES ('vendor1', 'http://example.org', timestamp '2014-01-01 01:01:01', 'product1', 'food', 1)

would suffice nicely.
