Yeah. 95% of the time, the answer to "how to use to_timestamp()" is
"don't". The native input converter for the date/timestamp/timestamptz
data types is perfectly capable of parsing most common date formats,
with a lot less muss and fuss than to_timestamp. At worst you might have
to give it a hint about DMY vs. MDY field ordering via the DateStyle
setting. If your input is YMD order then you don't have to worry about
that at all.
