Re: [GENERAL] Exporting data from view
I read recently about the efforts underway to COPY from a view, however I was wondering what the current best-practices are for being able to copy out of a view and import that data into an actual table elsewhere. I am currently doing psql -c SELECT ... and the using a bit of perl to transform that into something copyable (i.e. CSV), but is there a way to directly export the data in an easily importable form? psql -A -t -c select * from view; You can use -F to set the delimiter -o to specify an output file name (or just redirect stdout) etc. Try man psql To redirect it into a table, insert into table select ; between databases/systems psql -d DB -p port -A -t -c select * from view; | psql ... copy from stdin...; can work, as the psql extract can be written to generate the same format as copy from.

If you're going to create the table anyway, I'd use psql: psql -c COPY table TO STDOUT If you put CSV there you can get the output in CSV.
