[GENERAL] I need to ecrypt one column to an output file

[Ralph Smith]

I need to do a simple query and output to a file.
No problem.
But how do I encrypt one column's output?

There are lots of developer related links here, and info to "use the / 
contrib pgcrypto", but I'm not a PG developer and I failed to find any  
info on HOW TO USE that library function...

Thanks all,

Ralph Smith
