Is there an easy way to pipe a select statement's output to a file?

In psql, type \? and look at what \o and \g do. They both do it but slightly
differently.

That would depend on the client you're using.  psql can do it either
directly (using \o) or by piping its output:  psql -c "select * from
mytable;" mydb > out.txt

If you're using a programming library, I think you're on your own.

In psql you can use \o [filename] to direct query output to a file.

also,

$ psql  -c "select whatever_you_want from table_name" > outfile
