Hi!

Is your problem with how to generate the CSV file from Excel, or with
how to import it into PostgreSQL?

For generation in Excel, you can just use File->Save, and select CSV as
the format. You can use either CSV or tab delimited, really.

Then to get it into postgresql, use the \copy command in psql (I'm
assuming your client is on windows, since you're using Excel. \copy will
run the process from the client, and will load it into your sever
regardless of platform). You can specify which delimiter to use there,
etc. From the example below, I'd guess you want something along the line
of:

\copy "Flight Traffic" from yourfile.csv delimiter as ',' csv quote as
'"'

(might need some adaption, of course)


Loading 45,000 lines is trivial for copy, it shouldn't take noticable
time at all.


If you need to load things regularly, you can use the excel ODBC driver
and write a small script to transfer it over to get rid of the manual
steps.
