Right. Luckily, it is well-maintained - Tom Lane committed a fix based
on crypt_blowfish 1.1's on June 21st:
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=ca59dfa6f727fe3bf3a01904ec30e87f7fa5a67e
I've just e-mailed Tom to let him know about crypt_blowfish 1.2 with its
more elaborate changes, and to try to persuade him to include the runtime
quick self-test - to catch miscompiles, bugs potentially introduced in
re-users of the code (such as in a future revision of pgcrypto - who
knows), and to clean up the stack locations.
