Thanks very much for this. I am using 8.4.2.
This query works as you describe in pgAdmin.
I had tried it in the SquirrelSQL client, which is where it produced the
<Unknown(2,003)>
result.
Obviously, this is a SquirrelSQL problem at least in part.
What does <Unknown(2,003)> mean?
Thanks again for directing me to the doc's on dollar quoting.

The $re$ is just an arbitrary identifier for a dollar-quoted string
constant. See:
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html
Maybe you're on an old version which doesn't support dollar-quoted
strings?
On 8.3 for the above query, I get:
SELECT regexp_matches('foobarbequebaz', $re$(bar)(beque)$re$);
regexp_matches
----------------
{bar,beque}
