No, it means that if the primary is hit by a meteor and you promote
the standby, the data will not have been lost. The time between
the successful return of the commit on the primary and the time at
which the change becomes visible on the standby

Not necessarily. There has been discussion of adding a new mode
which will delay the commit on the primary until it is visible on a
synchronous standby, but I don't recall where that left off.

Hi,
I wanted to copy a file from local file system to postgres. I have
timestamp value specified as:
MMDDHH24 format -- for example:
2015072913 -- is July 29, 2015 at 13:00
how do I import this data into a timestamp field?
thanks, murali.

Yeah, the time component prevents you
Based on your PS asking about data types and commenting that you don't want
to put hour in a separate column, it sounds like this is a brand-new table
you're creating. If so, and if this is a one-time COPY operation, you can
create a text column for the initial import. Then after you're done
