Oliver showed you how to merge these together with the SQL concatenate
operator but there is another possibility.  PostgreSQL could use a
phone number type.  I have been meaning to write a user defined type
for some time but never seem to get around to it.  Maybe you could
give this a shot.  The examples in contrib should get you started.
Once finished you can make the phone # one column and split out parts
with various functions.  Don't forget to have a place for country code
and extension.
