How to build Golang windows/arm static binaries from linux

Alternate title: Cross compiling Windows/Darwin/Linux amd64/386/arm all from linux

After fumbling around trying to figure out the go toolchain and cross compilation configuration, I ran across the wiki page on Go's homepage. It's super helpful, and worked out of the box. I'm including the necessary scripts here in case they get changed or lost, and we can help Google find it (since it's the first real source I've found that "Just Worked"). http://code.google.com/p/go-wiki/wiki/WindowsCrossCompiling

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
