Thread: pgsql: Suggest shell here-documents instead of psql -c for multiple com

Suggest shell here-documents instead of psql -c for multiple commands.

The documentation suggested using "echo | psql", but not the often-superior
alternative of a here-document.  Also, be more direct about suggesting
that people avoid -c for multiple commands.  Per discussion.
