Sorry to have been so slow, but I think this is the crux of it:

A timestamp represents a moment in time, without storing any
precision information. These timestamp literals represent exactly
the same moment, and therefore have exactly the same internal
representation:

timestamp '2008-01-31 12:31:40.50'
timestamp '2008-01-31 12:31:40.500'
timestamp '2008-01-31 12:31:40.500000'

to_char turns that into a string of your chosen format.

I hope that helps.
