Subject: [PATCH] > I've been experimenting with pgcrypto 0.3 (distributed with
> Postgres 7.1.0), and I think I've found a bug. > > I compiled Pgcrypto with
OpenSSL, using gcc 2.95.4 and > OpenSSL 0.9.6a (the latest Debian 'unstable'
packages).
> web=> select encode(digest('blah', 'sha1'), 'base64');
> FATAL 1: pg_encode: overflow, encode estimate too small
> pqReadData() -- backend closed the channel unexpectedly.
> This probably means the backend terminated abnormally

> The connection to the server was lost. Attempting reset: Succeeded.
> Is this a bug? Can it be fixed?
