Wow, there's a name I haven't seen in years. I used to deal with
him often when he was at Sybase, and once or twice after he moved
to Sun. Sharp guy.

That suggestion makes a lot of sense to me. The curly-brace
escapes are in JDBC for portability, so this seems like a totally
appropriate use; it's surprising it hasn't come up before.

We already have code in the JDBC driver to recognize curly-brace
escape sequences. We just need to add "postgres" as another
keyword for such escapes and we can do what we like for the rest of
the escape sequence. A mnemonic, such as Lance suggests, does seem
like a good approach.
