I don't know if you've seen this link, but I should be useful.

I would do:
psql-> \i <file-path>\function.sql

I believe that:
psql-> \o filename
or from the command line you can get query results returned to standard out. And then you could
"pipe" the result to whatever you wanted.
$ psql -u <user> -d <mydb> -c "select * from test" | grep -e "hello world" > hello.txt

Well, I would run it to see if it was syntactically correct.
Then I would check to see if the results were as I expected.
Next I would execute the function using "explain analyze" to see if there are any preformance
issues that need to be resolved.
